Function
No connection
The rectified input voltage sensing pin. The pin is detecting the phase of dimmer
The rectified input voltage sensing pin. The pin is detecting the average AC 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
Gate driver output
Supply voltage of gate driver and control circuits of the IC
