Fairchild Semiconductor’s Demos DC-DC Conversion Solutions at APEC 2012

January 31, 2012

At APEC 2012, in booth #701, February 5-9, 2012, at Disney’s Coronado Springs Resort, Orlando, Fairchild Semiconductor will showcase high-performance point-of-load digital power solutions using an advanced configurable digital controller and DrMOS as well as Fairchild’s new power stage dual-asymmetric MOSFETs that address the power supply designers’ need for high power density and ease of design in notebook, point-of-load, server, gaming and telecommunication applications.

As requirements expand to provide more functionality in end systems, power engineers are being challenged with providing higher current output in less board area. The FDMS36xx family of power stage dual asymmetric MOSFETs provide higher current output and reduce your power supply area. These devices feature Integrated control (high side) and synchronous (low side) MOSFETs as well as a Schottky body diode in a single 5mmx6mm PQFN package. They reduce foot print area by 50% or more replacing two or three 5×6 components and provides the high power density for point of load and multi-phase synchronous buck DC-DC applications.

High efficiency, high current handling capability and small form factors are critical to power supply designers when selecting components for voltage regulator solutions. To meet this need, Fairchild Semiconductor developed its family of Generation II XS™ DrMOS [Integrated Driver + MOSFET] devices offering high efficiency and power density to enable designers to meet specific design needs for various applications. Generation II XS DrMOS devices, available in a small, 6mm x 6mm high performance clip PQFN package, feature higher system efficiency with over 91.5 percent heavy load efficiency at 12Vin, 1Vout, and 25A, and 94 percent peak efficiency. Generation II XS DrMOS can be operated at a 2MHz switching frequency and have up to 50A of current handling capability.

Are you ready for 2013?

December 6, 2011

We may be getting ready for New Year ’s Eve 2012, but power designers are already looking at 2013, since it will be a year of significant changes.

The EU eco-design directive ErP (Energy-related Products) requires the maximum power consumption of electronics devices in standby mode to be more stringent, decreasing from <1W in the year of 2010 to <0.5W in the year of 2013.

To achieve less than 0.5W standby power consumption remains a significant challenge for auxiliary power supply designs in applications such as PCs, game consoles and LED TVs.

If you are still looking for solutions to meet the challenge of 2013 ErP, here is one from Fairchild.

The FSB1×7H series, the next-generation green-mode Fairchild Power Switch (FPS^TM):

• Provides designers with No-Load Power Consumption < 50mW at 230VAC (EMI Filter Loss Included)
• Meets 2013 ErP Standby Power Regulation (< 0.5W at 0.25W Load) for Auxiliary ATX Power and LCD TV Power
• Eliminates X-Cap Discharge Resistor Loss with AX-CAP^TM Technology while still meeting IEC61010-1 safety requirement

Voltage-mode CRM PFC for lighting offers higher efficiency, improves reliability

December 1, 2011

When it comes to lighting, efficiency and reliability are critical. Critical-conduction mode (CRM) power factor correction (PFC) controllers are available with two different control modes: current-mode and voltage-mode.

Though current mode controllers have been used for a while now, voltage mode controllers offer important advantages-particularly for applications-such as lighting, where high-efficiency low THD and high power factor are becoming more of a premium. The newest voltage-mode controllers designed for lighting applications are specifically designed to maintain good power factor, low THD at light loads, zero overshoot at turn on, and a PFC-ready pin for power sequencing of downstream converters. Also, the new voltage-mode devices are conveniently designed to have backwards compatibility with older current-mode designs. This allows some of the benefits of this voltage-mode controller to be implemented in older designs without layout changes.

The main difference between a voltage-mode and current-mode controller is how the controller decides when to turn off the power MOSFET. For the current-mode controller, the MOSFET is turned off when the inductor current sensed through the current-sense resistor meets the desired current reference. Another major difference between the current-mode and voltage-mode PFC controllers has to do with the placement of its compensation network.

The newest generation of voltage-mode PFC controllers, such as the FL7930C from Fairchild, has added a few important features, such as a soft-start feature with zero overshoot, internal THD optimizer, and a PFC-ready pin. The THD optimizer allows for improved total harmonic distortion, while reducing the number of external components required and frees up an external pin which is being used for the PFC ready function. The PFC-ready pin tells the downstream DC/DC converter that the output voltage is at 89% of the set-bus voltage, making power sequencing much easier.

However, there’s a lot more to it. Read the full article at EE Times Design to learn the differences between these two controllers, how voltage-mode improves reliability and efficiency, and more about the FL7930C.

This article, posted in Power Management DesignLine, was written by Alexander Craig, Principal Application Engineer, at Fairchild Semiconductor.

Smaller, Louder Speakers Have Arrived!

October 12, 2011

Name that audio design challenge!

You’ve got it - Making Small Speakers Sound Louder and Better^TM, while minimizing impact on battery life is an important audio design challenge facing mobile engineers everywhere.

Fairchild has met this challenge with two product solutions: the FAB1200 stereo, a Class G ground-referenced headphone amplifier with integrated buck converter, and the FAB2200 audio subsystem with stereo Class-G headphone amplifier and 1.2W Class-D mono speaker amplifier.

Now that you’ve read about the mobile audio launch we can talk more about the products that make this launch important. By integrating leading circuit technologies into tiny, advanced packages, we provide mobile users significant advantages while reducing the size, cost and power of designs. Our mobile IP can be found in a majority of handsets around the world today.

The FAB1200 features a charge pump which generates a negative supply voltage that allows the headphone output to be ground-centered and capacitor-free, eliminating up to two external capacitors. The result of all these combined features is a reduced cost, extended battery runtime and excellent audio quality.

The mobile handset market never demands bigger devices and always demands longer battery life - the mobile audio launch from Fairchild delivers these needs. This device is ideal for excellent audio quality in mobile handsets, tablets, MP3s and other various portable media players.

The FAB2200 is an audio subsystem that combines a capacitor-free stereo Class-G headphone amplifier with a Class-D speaker amplifier. A proprietary integrated charge pump generates multiple supply rails for a ground-centered Class-G headphone output significantly reducing power dissipation when compared to Class-AB design implementations, while offering high power supply rejection ratio.

Answering the Call for “Smarter” Smartphones

October 6, 2011

Today’s smartphones have integrated themselves into our personal daily lives as well as our business lives. Smartphone sales are rising with every passing year, and show no signs of slowing down.

In his byline ‘Answering the Call for “Smarter” Smartphones’ in Electronic Design, Fairchild Semiconductor’s Edwin Lee discusses the smartphone and its continued dominance in the marketplace.

The article focuses on the importance of determining customer desires for their smart phones, and also provides an overview of the Android platform and the reasons behind its impressive ascent in the mobile world. It also explains the challenges around hardware specifications that are emerging due to ever-present consumer demand around performance.

If you’re a smartphone user, the chances of purchasing a slower-speed OS or a device with fewer options than before are slim to none. This is why designers have begun to address other applications such as security and monitoring control, mobile payment, and electronic money using near-field communication technology. For example, with HSDPA/Wi-Fi and a high-performance computation processor, smartphone users can access in-house Web cameras as a remote security control or baby monitor. These types of uses for a smartphone are what make the device so ubiquitous and successful.

Defining customer needs in terms of price and specification/performance can be difficult to pinpoint. Forecasts show that the low-range smartphone will drop to $100 or lower this year, and the mid-range smartphone with a Cortex application processor will cost $120 to $150.

This article also explores various Fairchild chips that mobile designers may want to consider for their current and future mobile projects. As smartphones continue to improve from a functionality standpoint, the hardware specifications require more power to achieve the performance. Enlarging the battery is the easiest method to meet this requirement, but that will likely mean tradeoffs in increased volume, weight, and materials cost.

Analog Switches in the Audio Path

September 30, 2011

As more and more people listen to music using mobile phones, audio engineers are working hard to deliver high-end audio quality.

A typical mid-to-high-end mobile phone design has multiple sources of audio from the baseband, application processor or standalone audio codec. Depending on how the phone is designed, sound may be routed through either a DC biased signal, or an AC (negative) signal. Depending on which one it is determines the need for a standard or negative analog switch.

In order to create the components, the audio engineer measures the total harmonic distortion (THD). Engineers usually budget up to 1% distortion for the audio path through the headphones. The level of THD is related to the on-resistance of the analog switch. As on-resistance increases, the THD’s on-resistant flatness also increases.

Once the placement of the analog switch has been determined, the primary routing component to consider is a low R_ON switch. The reason is that for audio signals the resistance of the analog path will contribute to the power losses of the overall system. Most new headphones are set to the negative analog switch in order to eliminate the need for the DC switches, thus keeping labor and materials costs down. Fairchild is a leader in making these negative analog switches, with a portfolio of products that save product power and money.

Eliminate Components and Save Costs for Welding Machine Applications

August 25, 2011

Posted for: Wanki Hong, Applications Engineer, Fairchild Semiconductor

Research is ongoing for a more efficient DC-ARC welding machine that combines low voltage with a large current. Various topologies are possible, but the Half Bridge is the most commonly used for a small capacity (under 230A) welding machine. When compared to a Full-Bridge topology with the same power rating, a Half Bridge design requires a greater amount of transformer wiring and a higher current capacity at the inverter. However, a Half-Bridge offers all the advantages of a simpler topology involving fewer components. In this case, data was acquired using an evaluation board with an output current of 140A and output voltage of 26V. The switching frequency was 20KHz.

When designing a welding machine, any temperature increase created by the duty cycle, for example at the transformer, should be within a set limit, if you want to avoid burning out the power supply. The duty cycle is expressed as a period of use at a rated output current during a period of 10 minutes. A 40% cycle, for example, would allow 4 minutes of use (at a rated output current of 140A), with 6 minutes for idling and cooling off.

An IGBT (Insulated Gate Bipolar Transistor), a voltage-controlled power transistor, was selected because of its superior performance to that of other bipolar transistors. It is a more cost-effective solution in applications where high current is combined with a high switching speed, and where the design goal is to reduce total device cost while optimizing thermal performance.

When the welder is operating, loss can be either a loss in conduction or a loss in switching (power on/off). There is a trade-off between the Vce(sat) and switching loss. If Vce(sat) is high, switching loss is low and vice versa. We concluded that the FGH40N60SMD (Field Stop Gen2), from Fairchild, showed faster switching characteristics at a lower Vce(sat), plus lower turn-off loss than alternative solutions.

When selecting the second rectifier diode for a welding machine, a lower Vf, Irr, and Trr would be ideal, but because there is a trade-off between Vf and Trr, designers should consider Vf and the reverse recovery characteristics of the diode. Generally, the second rectifier diode of a welding machine has a bigger conduction loss than the reverse recovery loss; therefore, we can conclude that Vf value is more important. For this reason, ultrafast diode FFA60UP30DN (30A dual diode), from Fairchild, was selected for this evaluation board.

Smart power modules becoming more efficient

August 4, 2011

Smart power switches help reduce losses up to 25% and allow the use of compact control solutions for BLDC motors.

Energy saving drives with brushless DC motors can be found everywhere, and the dust has settled somewhat, since the challenge consists of integrating a complex electronic control circuit into the motor, at realistic cost levels, to enable relevant advantages for the user. New power switch technologies can help, since they reduce losses and allow higher power density, enabling many savings.

We believe that further functionality will find its way into future smart power modules, and they will become even smarter. One possible approach is to integrate the control ICs, but additional protection functions or other power electronics components are possible. The key technology to enable these additions is a robust and flexible multichip packaging technology, as realized with Fairchild’s SPM® modules.

Pro audio techniques applied in mobile devices to improve sound quality

July 28, 2011

The mobile industry continues to reign supreme but it does have its challenges, one of which is audio quality.

Surprisingly, the audio quality of mobile phones is something that has been largely overlooked by both the mobile industry itself and a majority of the electronics industry- until now.

To meet these challenges, Fairchild recently announced two new product solutions: the FAB1200 stereo, a Class G ground-referenced headphone amplifier with integrated buck converter, and the FAB2200 audio subsystem with stereo Class-G headphone amplifier and 1.2W Class-D mono speaker amplifier.

In addition, Fairchild’s Earl Schreyer has just published an article on this topic in EE Times.

‘Pro audio techniques applied in mobile devices to improve sound quality’ discusses how these techniques can be applied and how they can aid in improving communication as well as entertainment in modern mobile devices.

The article focuses on Dynamic Range Compression (DRC) and limiting, which are traditional recording techniques used to raise the volume of subtle acoustic instruments (such as human voice), in order to bring out those subtleties, but at the same time automatically attenuate the dynamic peaks as not to overload the recording level. This technique is also used sometimes on certain instruments in live performance for the same reasons. If the lower level amplitudes can be raised while the higher level peaks are attenuated, the overall volume can be increased without distorting and over loading the speakers on the louder dynamics.

I recommend taking a moment to review Earl’s article. It’s already getting positive feedback from our colleagues in the electronics industry! And if you have any comments to share, please feel free to post them here.

How to Meet Three Key Requirements for Power Designers - Green Mode Fairchild Power Switch (FPS™) Provides the Technology and Process Advancements for Reliability

Mobile Audio Capabilities Bring Speakers to a Louder, Better Level

July 6, 2011

Fairchild Semiconductor recently launched a mobile audio campaign on June 6, which seeks to meet consumer demand for making small speakers sound louder and better. Moving into the mobile audio space is exciting for us, as we seek to address our customer’s challenges of providing louder audio and better audio quality while maintaining long battery runtimes.

Research has shown us that over 90 percent of people purchase a mobile phone based on its sound quality. In the age of the smartphone, people use the conference call speaker mode more than ever. On the go, it’s often used for music or movies, so with properly designed audio capabilities, end users want the best sounding handsets. 

Fairchild has a world-class supply chain resulting in a dependable high-volume supply of ICs to handset OEMs, and we’ve made the connections with leading mobile manufacturers to help them meet next-generation design challenges and maintain a competitive advantage. We are pleased to announce that Fairchild mobile audio ICs are in multiple Tier-1 handsets today and the design-ins are rapidly increasing.

Getting more technical now, our customers have a strict power budget to maintain. The higher your audio volume, the faster the battery drains, and that audio can consume over 10 percent of the phone’s power budget. Not surprisingly, our customers are pressuring their IC suppliers for lower power consumption to maintain longer battery life. Improving audio volume and quality while maintaining battery runtime requires either a battery capacity and size increase, or borrowing power from other functions. Fairchild’s mobile audio design team has proven that, through excellent design skills, we can maximize sound quality while minimizing the power impact, so the products you will see coming soon will not sacrifice sound quality or small battery size.

The tablet market, as we all know, is growing fast. Tablets take audio to a new level since they have more room for larger speakers, and a larger screen is associated with louder and better audio. As with handset OEMs, we are working with tablet manufactures to optimize their audio quality while maintaining battery life.

To learn more about the semiconductor technology that powers the products we use and makes them more energy efficient, visit Fairchild Semiconductor’s website at www.fairchildsemi.com.

Power Saving Features for BLDC Motor Controller

June 23, 2011

Saving energy while maintaining a small carbon footprint is of global concern today. Reducing environmental pollution to avoid climate change, optimizing energy efficiency, and conserving resources are just a few topics on the global agenda. If we all adopted the use of high efficiency motors and optimized controls, our dependency could be significantly lower.

According to research by the Electric Power Research Institute (EPRI), motors account for 51% of the world’s total energy consumption, at an annual cost of 95 billion U.S. dollars. The energy consumed by other sectors is comparatively lower. Lighting, for example, accounts for 19%, cooling and heating 16%, and Information Technology 14%. Clearly, there is a market necessity for an efficient and robust brushless DC motor controller—-the wave of the future. Fairchild Semiconductor offers advanced calculation tools that optimize efficiency, simplify the design process, and shorten time-to-market.

In fact, motors consume the most energy, no matter what the scenario - household or commercial - in which they are being used. In 2007the total electric power consumption of Taiwan was 117.2 billion KWH. Of that, motors consumed 82 billion KWH, accounting for 70% of the total. More energy efficient motors offer a significant savings in energy consumption.

Household appliances account for much of the energy used in the world, especially in North America. Motors used in these household appliances are categorized by type: AC or DC. DC can be categorized further to be brushed or brushless (BLDC). Recent years have brought about breakthroughs in technology and the production of BLDC motors. These motors are powerful, compact, and maintenance-free.

In comparison to other types of motors, such as AC and brushed DC, BLDC motors offer a higher level of technology and hence deliver higher value. Given the twin pressures to reduce energy consumption and protect the environment, BLDC motors are inevitably becoming the favored solution.

BLDC motors can be driven using several control schemes. Fairchild’s FCM8201 and FCM8202 motor controllers support both the most common and most acoustically quiet 3-phase modulation schemes: Trapezoidal and Sinusoidal. The controllers can selectively or automatically switch between these two schemes as required to optimally drive the connected motor. The FCM8201 and FCM8202 also includes several protective features which simplify the design of robust control circuitry with no software development required.

The FCM8201 and FCM8202 are capable of stand-alone operation with minimal discrete components. The FCM8201 has an on-board SPI interface which can be easily connected to an attached microcontroller. Such configurations allow the engineer to focus software development time and resources on the key aspects of the product being designed by offloading the motor control tasks to the FCM8201.

Detailed datasheets, thorough application notes, and powerful evaluation boards are available to support engineers interested in the fastest time-to-market while supporting leading-edge green technology.

Making Small Speakers Sound Louder and Better: RCR Wireless Reviews ‘the Audio Squeeze’

June 20, 2011

“We believe in turning the phone into a small boom box,” says Greg Davis, Senior Technical Marketing Manager for Audio Products and Signal Conditioning at Fairchild Semiconductor.

We had a discussion with Sylvie Barak of RCR Wireless last week that centered on our recent mobile audio launch. Sylvie was interested in hearing about past product lines and areas of focus, and she was interested to learn that Fairchild is in talks with tier one mobile handset manufacturers that will include our audio IC designs. These designs will be part of the next generation of great-sounding, smaller speakers.

Greg noted that with today’s drive for lower and lower powered devices, audio is certainly “getting the squeeze.” He’s absolutely right; audio consumes approximately 12% of today’s typical smartphone power budget and improving audio loudness and quality has tended to rely on increasing battery capacity and size or borrowing some power budget from other functions.

Luckily for handset manufacturers, and ultimately, the mobile audio consumer, Fairchild’s design team works relentlessly to achieve louder and better speakers, firstly through the use of a more efficient class-G, cap-free, ground-centered headphone amplifiers, and also through efficient class-D speaker amplifiers.

We’re looking forward to reviewing future mobile audio products, and maybe RCR Wireless will have more to say on that!

March 10, 2011

Come to electronica China to learn more about mWSaver™ technology from Fairchild Semiconductor at booth 1310.

mWSaver technology from Fairchild offers the best-in-class power savings for power supplies, with the fewest possible components. mWSaver technology integrates five patented technologies: off time modulation, JFET HV start-up and circuit, feedback impedance switch, HV discharge, and PSR control to drop out voltage; as well as burst mode operation and low operation current techniques. It is only by the unique integration of these technologies, leveraged together, that the most stringent standby specifications can be met.

While the best power supplies are more than 90 percent efficient, some are only 20 to 40 percent efficient, wasting the majority of electricity that passes through them. Power supplies can account for nearly 10 percent of the total residential electricity used yearly. Regulations and technology help to reduce standby power, but the increase in the number of appliances and equipment that consumes power continues to grow, especially in developing countries.

The FAN302HL controller also provides several protections. Cycle-by-cycle current limiting ensures the fixed peak current limit level, even if a short circuit occurs. The gate output is clamped at 15V to protect the power MOS from high gate-source voltage conditions. If either V_S OVP or internal OTP is triggered, the circuit enters Latch Mode until AC power is removed. Using the FAN302HL, a charger can be implemented with few external components and minimized cost, compared to a conventional design or a linear transformer.

Come to APEC 2011, booth 209, to learn more about the company’s innovative mWSaver™ technology offering best-in-class power savings for power supplies, with the fewest possible components.

Fairchild Discusses the FAN6755 Highly-Integrated Green-Mode PWM Controller at APEC 2011

March 1, 2011

At APEC 2011, booth 209, Fairchild will demo the highly-integrated green-mode PWM controller, the FAN6755. Fairchild’s PWM controllers have several features that enhance the performance of flyback converters. For example, to minimize standby power consumption, a proprietary adaptive green-mode function reduces switching frequency at light-load condition. The minimum PWM frequency is set above 23kHz in order to avoid acoustic noise problems. This green-mode function enables the power supply to meet international power conservation requirements, such as Energy Star^®.

The power loss caused by bleeding resistors is also eliminated due to the internal high-voltage startup circuitry. The FAN6755 uses the BiCMOS process, which allows an operating current of only 2mA resulting in less power consumption. The standby power consumption can be under 100mW for most of LCD monitor power supply designs.

Fairchild’s FAN6755 also integrates a frequency-hopping function that reduces EMI emission of a power supply with minimum line filters. Its built-in synchronized slope compensation achieves a stable peak-current-mode control and improves noise immunity. The proprietary, external line compensation ensures constant output power limit over a wide AC input voltage range from 90V_AC to 264V_AC.

There are also many protection functions that the FAN6755 provides. The internal feedback open-loop protection circuit protects the power supply from open feedback loop condition or output short condition. It also has line under-voltage protection (brownout protection) and over-voltage protection using an input voltage sensing pin (V_IN).

Visit our booth at booth, #209, at APEC 2011 to learn more about our innovative PWM controller technologies.

Fairchild to Demonstrate TinyBuck™ Regulators at APEC 2011, Booth 209

February 28, 2011

Fairchild Semiconductor is dedicated to providing diverse power products that are smaller than ever, and increasingly more energy efficient, in order to meet designer needs and ultimately, consumer demands. At this year’s APEC 2011, we’ll be discussing the family of TinyBuck™ synchronous Buck regulators. This product family enables power designers to achieve higher output current and high efficiency using less PCB space.

The TinyBuck family of 3A, 6A and 8A fully-integrated, synchronous Buck converters improves efficiency over a wide input voltage range in a variety of applications including servers, telecommunications, computing and medical.

As an example, the FAN21SV06 integrates a controller with optimized interconnects, synchronous MOSFETs and a bootstrap diode into one ultra-compact, 5mm x 6mm, MLP package and accepts input voltages from 6.5V to 24V. This configuration offers over 40% space savings compared to a discrete implementation and like other members of the TinyBuck family, the FAN21SV06 provides up to 95% efficiency compared to alternative solutions. With this new device, designers can fulfill high-current requirements in a small area with minimal external components to save cost. The cost of input capacitors is also reduced due to an externally synchronizable clock with master/slave provisions. 

The TinyBuck device also features a range of protection features including soft-start, Under- Voltage Lockout (UVLO), thermal shutdown, as well as over-voltage and over-current protection to guard against damage during fault conditions. A pre- bias startup takes place during soft-start conditions to regulate discharging of the output capacitor and protect the system ICs from damage. A TinyBuck reference design, the RD278, is also available to help designers develop highly efficient DC/DC conversion applications and bring those applications to market faster

We invite you to our booth, 209, at APEC 2011 to see power supplies like the FAN21xx and much more! Is this a solution that would be helpful to your designs?

At IIC China: FAN6920MR - Fairchild Controllers Provide Cost-Effective Design and Reduces External Components

February 22, 2011

What do All-In-One (AIO) PC power, Slim Pack PC adapters, LCD TVs and LED lighting designs have in common?

They all require a dual switch flyback topology that provides higher efficiency and increased energy savings required by government regulations – something that LLC or single flyback solutions cannot provide.

One product design engineers can use is the FAN6920MR, which is an integrated critical mode PFC and quasi-resonant current mode PWM controller. It meets regulatory requirements by providing >90 percent efficiency and <300mW at no load for increased power savings.

By combining Power Factor Correction (PFC) controller and quasi-resonant PWM controller, the FAN6920MR provides a cost-effective design and reduces external components.

For PFC, the FAN6920MR uses a controlled on-time technique to provide a regulated DC output voltage and to perform natural power-factor correction. Reduced input current distortion at zero-crossing duration to improve THD performance is the result of the FAN6920MR’s innovative THD optimizer.

For PWM control, the FAN6920MR provides several functions such as valley detection, green-mode operation, and high / low line over-power compensation to enhance the power system performance. Protection functions include secondary-side open-loop and over-current with auto-recovery protection; external auto-recovery triggering; adjustable over-temperature protection by RT pin; and external NTC resistor, internal over-temperature shutdown, VDD pin OVP, and DET pin over-voltage for output OVP, and brown-in / out for AC input voltage UVP.

Fairchild Global Power ResourceSM Center Delivers a Total Solution for Energy-Efficient LED Street Lighting

February 20, 2011

Fairchild Semiconductor’s China-based Global Power Resource^SM Center (GPRC) has developed a complete LED street lighting solution that provides high efficiency and outstanding thermal performance, as well as high reliability to increase the lifetime of street lamps.

This solution validates the strong energy-efficiency reputation Fairchild has by reducing power consumption in order to meet and exceed the increasing demand for greener electronics. This demand has been driven by consumers as well as governments and regulatory standards worldwide – including China’s central and provincial authorities and ENERGY STAR’s Solid-State Lighting (SSL) guidelines. 

The new solution features advanced critical conduction mode (CrCM) PFC, high-efficiency DC-DC and constant current control. This total solution includes two sub-solutions, either parallel or serial, within the same PCB layout delivering up to 91.26 percent and 92.6 percent efficiency respectively from AC input to the LED side, under 220V input voltage.

It significantly lowers component count by more than 20 for the parallel layout and 86 for the serial layout compared to conventional solutions. Fewer components, robust protection functionality and high LED fault tolerance capability make the solution very reliable. Fairchild GPRC engineers deployed a range of parts from the company’s portfolio to develop this total solution such as the FAN7930, an active power factor correction (PFC) controller designed for boost PFC applications operating in CrCM; the highly integrated Fairchild Power Switch (FPS™), the FSFR2100 offers everything necessary to build a reliable and robust resonant half-bridge converter.

In addition, Fairchild LED lighting solutions are available for applications with output power requirements ranging from <7W up to >100W.

IIC China Update: Simplify Smartphone Designs with Audio Jack Detection and Configuration Switch

February 20, 2011

How do you keep up with changing technology?

More and more people are using their smartphones for multimedia purposes – whether it’s watching videos on YouTube® or listening to their favorite songs, which in turn, mean users are plugging headphones into their smartphone for listening. This has taken off and grown exponentially as an “all-in-one” entertainment device. 

3.5mm audio jacks are the primary way for users to connect headphones into their smartphones – these jacks are also used to connect headphones with speakers in them, so consumers can talk “hands-free.”

The FSA8008 is an audio jack detector and configuration switch for 3 or 4 pole accessories. A switch within the FSA8008 eliminates pop and click as well as leakage current – for an enhanced consumer experience and additional battery power savings. This chip also eliminates the need for software to solve the send/end button problem – with this chip, if the button sticks there’s no issue and will always register a microphone, if a microphone is present.

The FSA8008 provides ease of design for engineers as well as cost and space savings, and of course it means a satisfied customer.

If you’d like to see this product demoed at IIC China, stop by booth 2J19!

electronica 2010 update: Fairchild Introduces Industry-First 2.8V to 36V Integrated Load Switches Provide Robust Protection and Simplify Power Management Design

November 10, 2010

This year at electronica, Fairchild introduced its AccuPower™ Load Switch Family. These switches are ideal for industrial, computing and portable designs. Participants can drop by Hall A. 4, Booth #506 and view this and the many other products that Fairchild will be exhibiting this year.

The AccuPower series is a family of current limiting load switches that provide full protection to systems and loads that may encounter large current conditions. The series contains a slew rate controlled N-Channel MOSFET which limits the amount of in-rush current. This protects from abnormalities on the main power supply rails.

Devices in the AccuPower series of load switches include the FPF2700, FPF2701 and FPF2702. Unlike current solutions in use today that require discrete MOSFETs plus external protection circuitry, devices in the AccuPower series of load switches feature built-in protections to eliminate as many as four additional devices, which saves over 70 percent board space. The switches in this family also feature under-voltage lock-out (UVLO) protection and thermal shutdown protection. Switch control is completed by a logic input (ON) capable of interfacing directly with the low voltage control signal. When the switch current reaches the current limit, the device operates in a constant-current mode to prohibit excessive currents from causing damage.

electronica 2010 update: Fairchild Engineering table focuses on Low Power

November 9, 2010

At electronica today, Fairchild demonstrated its latest technologies in Low Power Solutions at one of our multiple Engineering tables.  

At this table, we focused on 5W CC/CV Power Supply (5V/1A) with primary side regulation – where visitors saw such products as the FAN103. This third-generation Primary Side Regulation (PSR) and highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary TRUECURRENT™ technology of the FAN103 enables precise CC regulation and simplified circuit for battery charger applications.

Another area of interest that we focused on at this engineering table was 3.5W CC/CV Power Supply (5V/0.7A) with primary side regulation. The low power solution Fairchild will be highlighting for this is the FSEZ1317 – another one of our third-generation PSR and highly integrated PWM controllers. When using this solution, a low-cost, smaller, and lighter charger results, as compared to a conventional SSR (secondary side regulated) design or a linear transformer. To minimize standby power consumption, the proprietary green mode provides off-time modulation to   decrease PWM frequency under light-load conditions.

The FSQ500L  and FSQ500N are solutions that addresses both 2W Auxiliary Power Supply (5V/400mA) and 1.2W Buck Converter (12V/100mA). The FSQ500L is specially designed for a replacement of linear power supplies with low cost. This device combines current-mode PWM with a SenseFET. The integrated PWM controller features include: a fixed oscillator, Under Voltage Lockout (UVLO) protection, Overload Protection (OLP), Leading-Edge Blanking (LEB), an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection with hysteresis, and temperature-compensated precision-current sources for loop compensation.

Also at this table, we addressed 40W Auxiliary Power Supply (19V/2.1A) such as the FAN6862. This is a highly integrated PWM controller which provides several features to enhance the performance of flyback converters. To minimize standby power consumption, a proprietary green-mode function provides off-time modulation to continuously decrease the switching frequency under light-load conditions. This green-mode function enables power supplies to meet international power conservation requirements. The FAN6862 is designed for SMPS and integrates a frequency-hopping function that helps reduce EMI emission of a power supply with minimum line filters.

Lastly, we featured solutions that addressed 19W Auxiliary Power Supply (5V/2A) (12V/0.85A) such as the FSL136MR. This solution integrates PWM and SenseFET and is specifically designed for high-performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL136MR includes integrated high-voltage current-mode PWM control block and    an avalanche-rugged SenseFET. When compared to a discrete MOSFET and controller or RCC switching converter solution, the FSL136MR reduces total component count, design size, and weight; while increasing efficiency, productivity, and system reliability.
