hi,
Find the attached schematic, i am using this circuit to drive high side n-channel mosfet...
i am feeding the PWM signal from a ATMega 88 controller of 20KHz varing duty cycle from 0-90%.but the driver circuit works till 70% if i try to feed above 70% it is folding back WHAT MIGHT BE THE REASON FOR this behavior what is the solution to come out from this problem...??????? using pulse transformer
Regard's
