HBS SERIES - 75 WATT
DESCRIPTION
FEATURES
HBS single output DC/DC converters provide up to
75 Watts of output power in an industry standard
half-brick package and footprint. These units feature
excellent efficiency, Class A conducted noise specs, and
fixed switching frequency. The HBS features open-frame
packaging, along with planar magnetics to provide
maximum useable power with minimal thermal
constraints. The HBS converters are especially suited to
telecom, networking, and industrial applications, and are
fully compatible with production board washing
processes.
