		<description><![CDATA[Dear Dr. Efficiency, I used a synchronous rectifier MOSFET with large current and low RDSON in a forward converter structure for synchronous rectification (SR) and expected there would be a significant improvement in efficiency.  However nothing happened.  Why was that?  I thought that the SR MOSFET should make a significant contribution to efficiency improvement.  - [...]]]></description>

		<description><![CDATA[Dr. Efficiency,
Why does my power supply’s output suffer duty cycle fluctuation? I’m experiencing one big duty cycle followed by a small duty cycle. The pulses with large duty cycles almost occupy the maximum T(on) time and only those with small duty cycles can be modulated. My power supply uses a UC3842 PWM controller. Both the [...]]]></description>

Greetings to Dr. FAE,
I notice many of your competitors do not use feedback loops in their reference designs. You guys have some parts with no feedback loop (like the tiny 0.6A 6MHz FAN5361 regulator http://www.fairchildsemi.com/pf/FA/FAN5361.html) while some parts, like your new 4A integrated regulator FAN21SV04 (http://www.fairchildsemi.com/pf/FA/FAN21SV04.html) do have an external feedback loop. I wonder: why [...]]]></description>
