APPLICATIONS

The A_D-W25 & B_LD-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.
