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
