Pin Description
Connected to the auxiliary winding, this pin detects the core reset
event.
Also, injecting a negative voltage smaller than 0.3 V on this pin will
perform over power protection.
Hooking an optocoupler collector to this pin will allow regulation.
This pin monitors the primary peak.
The controller ground
The driver ’s output to an external MOSFET
This pin is connected to an external auxiliary voltage.
This pin observes the HV rail and protects the circuit in case of low
main conditions. It also offers a way to latch the circuit in case of over
voltage event.
A capacitor connected to this pin acts as the timing capacitor in fold-
back mode.
