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.
