FEATURES

● 2:1 wide input voltage range

● DIP package

● Efficiency up to 81%

● 1500VDC isolation

● Short circuit protection

(automatic recovery)

● Operating temperature: -40°C to +85°C

● Internal SMD construction

● No heat sink required

● MTBF>1,000,000 hours

● RoHS Compliance

APPLICATIONS

The WRA_(M)P-3W & WRB_(M)P-3W Series

are specially designed for applications where a

wide range input voltage 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

wide range (voltage range

≤2:1);

2) Where isolation is necessary between input

and output (isolation

≤1500VDC);

3) Where the regulation of the output voltage and

the output ripple noise are dem anded.
