APPLICATIONS
The A_S-W25 & B_LS-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.

1)
Where the voltage of the input power

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.
