HBS SERIES - 50 WATT
DESCRIPTION
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.
