∗2
∗1 Pulse noise is not included.
∗2 The output ripple voltage may vary depending on the capacitance, environment, and location of peripheral components. 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.

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.
