Re: TI UC2710 vs. Microchip TC4422 FET drivers

I'm surprised you actually tried both as everyone in the industry knows the
TC4421 and TC4422 are the work horses for FET drivers.

However, be careful, as at high frequency (>300 kHz) your gate capacitance
could draw some serious current and you'll have to cool these things.

I use them to drive IXFN24N100 1000V FETs at around 270kHz and these things
get smokin' hot.  Requires fan cooling.
