Especially right attention has to be paid to aluminum electrolytic capacitor, because ESR changes greatly at the time of the low temperature and output ripple voltages increase. Application Circuit Output Power (W) Max. 16.0 800 VD 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 (750kΩ) 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.
