HBS single output DC/DC converters provide up to • Industry Standard Half-
Brick
75 watts of output power in an industry standard
half-brick package and footprint. These units feature • Open-Frame Packaging
excellent efficiency, Class A conducted noise specs, and • 100°C Baseplate Operation
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.
