1S8W4_2RP series

1W - Dual/Single Output - Wide Input - Isolated & Regulated

DC-DC Converter

1 Watt

Ultra Wide 4:1 Input

Voltage Range

High Eﬃciency up to 81%

1W Single and Dual outputs

I/O Isolation 2kVDC

Operating Temperature

Range: -40°C to +100°C

Continuous Short Circuit

Protection (SCP)

The 1S8W4_2RP 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.

Remote ON/OFF Control

These products apply to:

1) Where the voltage of the input power supply is wide range

(voltage range ≤4:1)

2) Where isolation is necessary between input and output

(isolation voltage ≤2000VDC)

3) Where the regulation of the output voltage and the output ripple

noise are demanded
