SenseFET drain. High-voltage power SenseFET drain connection.
Ground. This pin is the control ground and the SenseFET source.
Power Supply. This pin is the positive supply input. This pin provides internal operating current for
both startup and steady-state operation.
Feedback. 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 6V, the overload protection
triggers, which shuts down the FPS.
Sync. 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 1.2V/1.0V.
Startup. This pin is connected directly, or through a resistor, to the high-voltage DC link. At
start-up, the internal high-voltage current source supplies internal bias and charges the external
capacitor connected to the V
It is not recommended to connect V
