APPLICATIONS
The A-XS-W25&B-XLS-W25 Series are
specially designed for 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.
