I am "high-side" switching a P-FET at several hundred Khz. The source
is connected to +12V and I need to pull the gate to Vsource minus 10V
or so to fully turn it on. I'm using a ground-referenced, 5V swing PWM
circuit to perform the switching.
I need to really "slam" the gate of the FET to reduce the switching
time. In the past, I used a high-speed op-amp to provide the
necessary gate drive, but don't feel comfortable with this approach
because the output current required stresses the op-amp, and the 5V
swing probably doesn't make the input too happy either.
Does anyone know of a SMT FET driver that has a push-pull output,
100mA of drive and can tolerate a 16V supply? Any other ideas?
TIA
