Connecting an NTC to this pin allows reducing the output current down to 50%
of its fixed value before stopping the controller. A Zener diode can also be
used to pull−up the pin and stop the controller for adjustable OVP protection
Connected to the auxiliary winding, this pin detects the core reset event.
This pin monitors the primary peak current
The controller ground
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.
A capacitor connected to ground select the soft−start duration.
