OBS SERIES  
25 WATT  
Powering Communications and Technology  
DESCRIPTION  
OBS single output DC/DC converters provide up to 25 Watts  
of output power in an industry standard package and  
footprint. The OBS units feature excellent efficiency, six-  
sided shielding, and fixed switching frequency. With 100°C  
case operation, the OBS converters are especially suited to  
telecom, networking, and industrial applications. These  
units are 100% surface-mount construction and fully  
compatible with production board washing processes.
