No connection
The rectified input voltage sensing pin. The pin is detecting the
instantaneous rectified sine waveform of input voltage
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
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
