This pin is the control ground and the SenseFET source.
This pin is internally connected to the inverting input of the PWM
comparator. The collector of an opto-coupler is typically tied to this
pin. For stable operation, a capacitor should be placed between this
pin and GND. If the voltage of this pin reaches 4.7V, the overload
protection triggers, which shuts down the FPS.
This pin is internally connected to the sync-detect comparator for
valley switching. In normal valley-switching operation, the threshold of
the sync comparator is 0.7V/0.1V.
This pin is the positive supply input. This pin provides internal
operating current for both startup and steady-state operation.
High-voltage power SenseFET drain connection.
This pin is connected directly, or through a resistor, to the high-
voltage DC link. At startup, the internal high-voltage current source
supplies internal bias and charges the external capacitor connected
to the V
