Operating Temperature Range:
The 1S8W_3RP series is a family of cost effective 1W single & dual output
DC-DC converters, 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.
Wide 2:1 input voltage range
Efficiency up to 77%
1W Single and Dual outputs
I/O Isolation 3kVDC
-40°C to +85°C
Continuous Short Circuit
Protection (SCP)
Remote ON/OFF Control
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
voltage ≤3000VDC)
3) Where the regulation of the output voltage and the output ripple
noise are demanded

* Input filter components are required to help meet conducted emission Class A,
which application refer to the EMI filter of design & test configuration.
** An external filter capacitor is required if the module has to meet IEC61000-4-4
and IEC61000-4-5.
