Electrical Characteristics
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.

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.
