Pin Function Description
SenseFET Drain.
High voltage power SenseFET drain connection. This pin is
designed to drive the transformer directly.
Ground.
Control ground and the SenseFET source.
Supply Voltage.
Supply input. This pin provides internal operating current for
both start-up and steady-state operation.
Feedback.
Internally connected to the inverting input of the PWM comparator.
For stable operation, a capacitor should be placed between this pin and GND.
If the voltage of this pin reaches 7.5V, the overload protection is activated,
resulting in shutdown of FPS.
Soft Start and Sync.
For soft-start and synchronization to the external sync
signal.
