Description
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.
