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 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 7.5V, the over load protection triggers resulting in
shutdown of the FPS.
This pin is for the soft start. Soft start time is programmed by a capacitor on
this pin.
