Patent ID: 8304888

Claim:
A power converter comprising: a dielectric substrate having a first side and a second side opposite the first side; a high-side metal-oxide-semiconductor field-effect transistor (MOSFET) die embedded in the dielectric substrate; a low-side MOSFET die embedded in the dielectric substrate; an integrated circuit (IC) die, having a top and a bottom, the bottom surface mounted on the first side of the dielectric substrate and electrically coupled to the high-side MOSFET die and low-side MOSFET die, wherein, in cross section, the IC die at least partially overlaps each of the high-side MOSFET die and low-side MOSFET die; an electrically insulating material disposed on the top of the IC die and at least a portion of the first side of the dielectric substrate; a plurality of conductive regions on the second side of the dielectric substrate for mounting of the dielectric substrate, wherein one of the plurality of conductive regions on the second side of the dielectric substrate is electrically coupled to a source of the high-side MOSFET die and to a source of the low-side MOSFET die; a plurality of through hole vias disposed within the dielectric substrate, at least one of the plurality of through hole vias electrically coupling the IC die to at least one of the plurality of conductive regions.
