Abstract

A power semiconductor system includes a power stage module having one or more power transistor dies attached to or embedded in a first printed circuit board, and an inductor module attached to the power stage module and having an inductor electrically connected to an output node of the power stage module. The inductor is formed from a ferrite sheet embedded in a second printed circuit board and windings patterned into the second printed circuit board. Corresponding methods of manufacturing the power semiconductor system and the inductor module are also disclosed.
