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 includes windings patterned into a second printed circuit board of the inductor module.

Power semiconductor system having an inductor module attached to a power stage module

A method of manufacturing a power semiconductor system includes providing a power module having one or more power transistor dies and attaching an inductor module to the power module such that the inductor module is electrically connected to a node of the power module. The inductor module includes a substrate with a magnetic material and windings at one or more sides of the substrate. Further methods of manufacturing power semiconductor systems and methods of manufacturing inductor modules are also described.
