Mô tả:

1 Drain High voltage power SenseFET drain connection. 2 GND This pin is the control ground and the SenseFET source. 3 Vcc This pin is the positive supply input. This pin provides internal operating current for both start-up and steady-state operation. 4 Vfb 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 7.5V, the over load protection triggers resulting in shutdown of the FPS. 5 Soft-start This pin is for the soft start. Soft start time is programmed by a capacitor on this pin.
