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, 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.
