APPLICATIONS  
The WRA_CS-2W & WRB_CS-2W 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:  
9
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≤1500VDC);  
3) Where the regulation of the output voltage  
and the output ripple noise are demanded.

When open or high impedance,the converter  
work well; When this pin is ‘high’; the converter  
shutdown; It should be note that the input current  
(Ic) should between 5-10mA, exceeding the  
maximum 20mA will cause permanence damage  
to the converter. The value of R Can be derived as

However, the capacitance of the output filter  
capacitor must be proper. If the capacitance is too  
big, a startup problem might arise. For every
