Abstract

A multi-phase DC-DC converter includes a substrate having opposing first and second sides, a plurality of power stage packages attached to the first side of the substrate, each power stage package including active semiconductor components operable to provide an output phase of the multi-phase DC-DC converter, and a coupled inductor attached to the first side of the substrate and at least partly covering two or more of the power stage packages. The coupled inductor includes separate windings wound on the same core. Each winding of the coupled inductor electrically connects an output of one of the power stage packages at least partly covered by the coupled inductor to a metal trace on the substrate such that the outputs of the power stage packages at least partly covered by the coupled inductor are electrically connected to the same metal trace on the substrate.
