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, sixsided 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.
