    Hello people, I just wanted to know if there are any good chips to drive the gate of a high-side MOSFET, with input fed from microcontroller PWM output?
    Or do anyone of you have idea how to build a discrete gate drive?
    *Personally i tried optocoupler (optoisolator) with bootstrap, but obviously the optocoupler's rise and fall times are the bottleneck, limiting maximum switching frequency.*
    (For switching of around 60kHz)

    Thanks!
