Brown−Out
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.
Pulling this pin down with an NTC or up with a zener diode
allows to latch the controller.
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 foldback mode.
