Function
This is the secondary side 12V output voltage
control terminal. Insert the output smoothing
capacitor 1000µF between GND.
2
GND
This is the GND terminal for the secondary
side 12V output.
5
Vi(-) This is the primary side input minus terminal.
6
VDD This is the internal circuit power supply terminal.
This is the built-in FET of drain terminal. The primary coil
8
VD ^{minus side of the external transformer, and the snubber}
circuit for noise reduction are connected to this.
Please verify operation and characteristics in the customer's circuit before actual usage.
Ensure that the load current does not exceed the maximum rating.
