Thanks for the website. My design is similar to FC's light dimmer controller since it uses a simple square/triangle wave generator and a comparator to produce the PWM square wave. I just feed the output into a Darlington stage and then some small push-pull mosfet drivers that feed drive the final large mosfets. I get a nice PWM square wave at 20KHZ. I'm working on stability at this point (I burned up one final-stage mosfet during testing).
