WRF/WRE****S-1W Series
Design & Feature Considerations
1. Input/Output Ripple Reduction
Reduce output ripple, it is recommended to use capacitors at the input/output.
It is recommended to use 10uF~100uF capacitors at the input; 3.3~22uF capacitors at the output.

2. Overload Protection
Tthe products provide protection against overload, the unit is equipped with internal current limiting circuitry .
3. Remote On/Off (CTRL Terminal)
When open or high impedance, the converter work well; When this pin is high,t he converter shut down; It should be note that
the input current should between 5-10mA,exceeding the maximum 20mA will cause permanence damage to the converter.
The value of R can be derived as follows:
R = VC VD 1.0
IC
Note
1.To ensure this module can operate efficinetly and reliably,During operation,the minimum output load is not less than 10% of the
full load.
2.Other input and output voltage may be available, please
