Pin Description

Pin Number

Pin Name

Function

No connection

The rectified input voltage sensing pin. The pin is detecting the

instantaneous rectified sine waveform of input voltage

VPK

The rectified input voltage peak value sensing pin. The pin is detecting

the rectified sine waveform peak value of input voltage

Primary current sensing

This pin captures the feedback voltage from the auxiliary winding. FB

voltage is used to control no load output voltage and determine

acceleration stop point at start-up phase

GND

Ground. Current return for gate driver and control circuits of the IC

OUT

Gate driver output

VCC

Supply voltage of gate driver and control circuits of the IC

VPK

GND

OUT

VCC
