HBS033YE-A General 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.
