Description
MCD10037 Rev. 1.0
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.
