I/O Description
P Internal Gate Driver Power Supply
P IC DC power supply Input
Inverting input of error amplifier (EA). Connected to resistor divider from
I primary sensing winding reflecting output voltage. PWM duty cycle is
determined by EA output and current sense signal at pin 4.
I Current sense input
O
HV MOSFET Drain Pin. The Drain pin is connected to the primary lead of
the transformer
