Driving dual switch PWM
Driving dual switch PWM
(OP)
I'm pretty new to PWM design, and I haven't seen any examples of how to drive a dual switch PWM. Every example I've seen seems to only drive a single mosfet tied to ground. No matter what I do I can't seem to get the switches working, at least in the simulator.

What I want is both switches to turn on at the same time, turn off at the same time. But I can't even get them to turn on. What do I need to do in this situation?

IR2103 (high side low side driver) looks like it should work great. Can't find a regular spice model for it though. Tried using the pspice model that IR provides but it makes multisim crash.
Guess I'll order them and bread board it to see if I have the layout correct.
