HBS SERIES - 50 WATT
DESCRIPTION
FEATURES
HBS DC/DC converters provide up to 50 Watts of
output power in an industry standard half-brick footprint.
The HBS units feature excellent efficiency, Class A
conducted noise specs, and fixed switching frequency.
The HBS, using open-frame packaging, along with planar
magnetics provides maximum useable power with
minimal thermal constraints. The HBS series is
especially suited to telecom, networking, and industrial
applications.
