Description
Ground . This pin is the control ground and the SenseFET source.
Power Supply . This pin is the positive supply input, which provides the 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.
No Connection.
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
external capacitor connected to the V CC pin. Once V CC reaches 12V, the internal current
source (I CH ) is disabled.
SenseFET Drain. High-voltage power SenseFET drain connection.
