APPLICATIONS

The IB_LT-1W 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

≤ ±5%);

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.
