Connected to the auxiliary winding, this pin detects the core reset event.
The controller ground
This pin monitors the primary peak current
The current capability of the totem pole gate drive (+0.3/−0.5 A) makes it suit-
able to effectively drive a broad range of power MOSFETs.
This pin is connected to an external auxiliary voltage.
This pin observes the HV rail and is used in valley selection. This pin also
monitors and protects for low mains conditions.
