Function This is the output detection terminal. This is the output detection terminal. This is the primary side input minus terminal. Feedback terminal This is the start terminal. Connect this via the external resistor (750k) to Vi (+). This is the built-in FET of drain terminal. The primary coil minus side of the external transformer, and the snubber circuit for noise reduction are connected to this.
