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