Hello,
The attached hi side FET driver circuit is blowing the FET up repeatedly in the lab. The circuit is for a hi side FET of a Buck converter, but the FETs are blowing up even when the FET is pulsed without there being any input voltage to the buck converter.
The attached Ltspice simulation shows no problem whatsoever with this circuit, even when the duty cycle suddenly jumps from zero to 80%.
Do you know what’s wrong?
