Abstract
In an embodiment, a DC-DC power conversion circuit with a step-down conversion ratio of at least 12:1 is provided. The DC-DC power conversion circuit includes a half-bridge circuit arrangement, a resonant capacitor and a module including a hybrid transformer. The hybrid transformer includes a magnetic core and a primary winding electrically coupled in series with a secondary winding. The module further includes a synchronous rectifier having an output coupled between the primary winding and the secondary winding of the hybrid transformer, and an output capacitor coupled with an output of the secondary winding.
