Abstract

See full text

A DC-DC converter includes a substrate having opposing first and second sides, a first discrete power stage transistor die attached to the first side of the substrate and including a high-side power transistor, and a second discrete power stage transistor die attached to the first side of the substrate and including a low-side power transistor electrically connected to the high-side power transistor to form an output phase of the DC-DC converter. The DC-DC converter further includes an inductor attached to the first side of the substrate so as to electrically connect the output phase to a metal output trace on the substrate. The inductor at least partly covers at least one of the first and the second discrete power stage transistor dies.
