applications where a group of polar power supplies are
isolated from the input power supply in a distributed power
supply system on a circuit board. These products apply to:
1) Where the voltage of the input power supply is fixed
(voltage variation
≤ ±10%);
2) Where isolation is necessary between input and output
(isolation voltage
≤1000VDC);
3) Where the regulation of the output voltage and the output
ripple noise are not demanding.
Such as: purely digital circuits, ordinary low frequency analog
circuits, and IGBT power device driving circuits.
