With the increasing popularity of LED lighting applications, designers face challenges ranging from design complexity and the need for high system efficiency to limited PCB space and the management of multiple vendors to meet all of their design requirements.
At APEC 2012, in booth #701, February 5-9, 2012, at Disney’s Coronado Springs Resort, Orlando, Fairchild Semiconductor will showcase its broad portfolio of LED lighting solutions for low-, mid- and high-power lighting applications.
On display at the show is the FL7701 Smart Non-isolated Buck LED Driver with power factor correction (PFC). The device uses a digital technique that allows it to automatically detect the AC input voltage condition, allowing it to create a special internal reference signal that results in high power factor correction. The FL7701 will also work from a DC input voltage condition, automatically sensing AC versus DC input voltage conditions.
The FL7701 combines high functional density in a small form factor that provides designers up to 20 percent lower bill of material (BOM) costs and up to 60 percent board space savings. This combination creates a solution suitable for the space-constrained PCB sizes found in LED lighting applications and supports analog dimming.
Fairchild’s LED lighting solutions feature integrated components in a single IC, using highly efficient and effective technologies for power ranges that are 1W and above. Fairchild offers multiple topologies, which provide energy efficient solutions for low-, mid- and high-power lighting applications. These topologies provide high power factor and low total harmonic distortion, enabling extended system life and reduced lifetime cost while meeting global energy regulations.

Fairchild Semiconductor: The Right Technology for Your Success™
Global attention continues to focus on the methods for achieving low power consumption and high efficiency. Lighting represents nearly 20% of the worldwide consumption of electrical resources and advancements in lighting can have a tremendous impact.
LED solid-state lighting (SSL) is environmentally friendly for the global environment. It has a smart form factor, long life, high conversion efficiency, and substantially reduces power consumption up to 80% or 90% compared to traditional incandescent lighting.
LED drivers play an important role in LED SSLs, as these drivers provide accurate current to maintain a stable brightness. However, the traditional approach of the LED driver used a secondary feedback circuitry for driving LED’s voltage and current. This secondary feedback circuit increases the cost and size.
Read this article in Hearst Electronic Products, which describes a patented primary-side regulation (PSR) technology. This PSR controller precisely regulates the voltage and current of the LED driver in the primary side of the transformer without the need for secondary feedback circuitry. It includes a frequency-hopping technique to reduce EMI and a green mode function to reduce standby power losses. With this approach, a PSR charger can achieve a smaller form factor, lower standby power and higher efficiency compared with conventional designs, such as ringing choke converter (RCC) and traditional PWM.
Participants at electronica 2010 can stop by our Fairchild booth (Hall A4, Booth #506) and see our lighting demo where we will be focusing on solutions for LED street lights.
Here, we’ll provide a detailed look at our solutions like the FSFR2100. This product is a highly integrated power switch designed for high-efficiency half-bridge resonant converters. The FSFR2100 combines power MOSFETs with fast-recovery type body diodes, a high-side gate-drive circuit, an accurate current controlled oscillator, frequency limit circuit, soft-start, and built-in protection functions.
The high-side gate-drive circuit has a common-mode noise cancellation capability, which guarantees stable operation with excellent noise immunity. The fast-recovery body diode of the MOSFETs improves reliability against abnormal operation conditions, while minimizing the effect of the reverse recovery.
Participants will also see how using the zero-voltage-switching (ZVS) technique dramatically reduces the switching losses and how efficiency is significantly improved. The ZVS also reduces the switching noise noticeably, which allows a small-sized Electromagnetic Interference (EMI) filter.

The power requirement of LED street lamps being used in China falls in the range of 100~250W. It is widely agreed that if used properly, these kinds of LED street lamps deliver many advantages. What I want to explain here is the ways to make it possible for these lamps to deliver those advantages. The key factors to be considered are high efficiency, power, reliability and cost-effectiveness.
Some low-power lighting requires PFC, while high-power lamps usually require PFC combined with DC/DC requirements. In China where the AC line voltage is 220V, Boundary-Conduction Mode (BCM) PFC controllers, such as the FAN7530 and the FAN6961, become the ideal choice to maintain a balance between the efficiency and performance-cost ratio. These solutions only need a few components.
Low Rds(on) SupreMOS(TM) MOSFETs, can further decrease switch and conduction loss. When used at the boost output, the HyperFAST 2 high voltage diode family with lower Vf can also lower the conduction loss of the diode itself.
For DC/DC topology, there are many choices such as quasi-resonant (QR), double transistor forward (DTF), active-clamp, LLC and asymmetrical half-bridge (AHB). High-power lighting applications, for example in a 100W lamp, where the output voltage is usually a little high, QR working with a synchronous rectifier can achieve up to 92.5% of total efficiency. Moreover, Fairchild has integrated QR and BCM PFC into one package (the FAN6921), reducing external components and simplifying the control.
Another popular topology is zero voltage switch (ZVS). Both an LLC and an AHB can have their two bridges working in zero voltage by implementing a simple circuit. When using Fairchild’s highly-integrated solution (for example, a LLC controller and two MOSFETs in FSFR; an AHB controller and two MOSFETs in FSFA2100), the circuit can be further simplified, with few external components. And the body diode of the MOSFET has good fast recovery characteristic, which can reduce the possibility of short-through, yet provide high reliability with high efficiency. When the output voltage is high, an LLC is the better option; when the output voltage is low, an AHB is more suitable for implementing a self-driven synchronous rectifier, and both can achieve over 93~94% efficiency.
The above solutions are highly integrated solutions and require just a few components, thus delivering high efficiency, high power density, optimized thermal performance as well as high reliability.
