High voltage power SenseFET drain connection.
This pin is the control ground and the SenseFET source.
This pin is the positive supply input. This pin provides internal operating current for
both start-up and steady-state operation.
This pin is internally connected to the inverting input of the PWM comparator.
The collector of an optocoupler 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 7.5V, the over load protection triggers , which results in the FPS
shutting down.
This pin is internally connected to the sync detect comparator for quasi-resonant
switching. In normal quasi-resonant operation, the threshold of the sync
comparator is 4.6V/2.6V. Whereas, the sync threshold is changed to 3.0V/1.8V
in an extended quasi-resonant operation.
