Description
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, providing internal operating current for
both start-up 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 pro-
tection triggers, which shuts down the FPS.
Sync . This pin is internally connected to the sync-detect comparator for quasi-resonant switch-
ing. 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
startup, the internal high-voltage current source supplies internal bias and charges the exter-
nal capacitor connected to the V CC pin. Once V CC reaches 12V, the internal current source is
disabled. It is not recommended to connect V str and Drain together.
