i made 220V AC to 12V DC 5A SMPS based on UC3842 using forward converter. schematic attached. supply's output voltage is ok and on no load (except indication led) pwm duty cycle is 1.1% with no mosfet heating (IRF740), but when loaded with even a little load of < 500mA, mosfet heats up although...
Hello
I am using a MOSFET driver circuit with SI2303 as p-channel mosfet and SI2302 as n-channel mosfet.
I have given control signal (of 5V) on the gate of n-channel mosfet to turn-on and off the p-channel mosfet.
However, the p-channel mosfet is not getting off and I am constantly finding...
