APPLICATIONS  
2.5  
4.5  
This WRN series is a high performance  
2.5V to15V,2Amp,12-Pin SIP (single in-line  
package).Integrated switching regulator  
(ISR),Synchrotron-rectified design yields  
excellent efficiencies up to 97%.Short  
circuit protection with crowbar function to  
reduce the short circuit current to under  
50mA of input current.
