Connect the positive and negative terminals of the output or the auxiliary winding to the VDD and VS pins, respectively. Parallel the VS pin and VD pin as the Source and Drain of SR Mosfet in the flyback circuit. Preset the input voltage of flyback converter to the normal input range, and then turn off the power supply. Turn the power supply on. The IC will automatically starts up and works as an ideal diode.
