Abstract
A power converter module includes a ground terminal, an input voltage terminal configured to receive a raw input voltage, and an interconnection terminal configured to provide a regulated output voltage to a load such as a SOC or SIP system to be powered. A voltage regulator is connected to the ground terminal and the input voltage terminal. An inductor has an inductor output connected to the interconnection terminal.

- a voltage regulator connected to the ground terminal and the input voltage terminal, wherein the voltage regulator comprises a first switch and a second switch;
- an inductor having an inductor output connected to an interconnection terminal, wherein each of a first switch and a second switch of the voltage regulator are stacked directly over a top side of the inductor such that the inductor is positioned directly between the voltage regulator and a substrate, wherein the inductor is stacked directly over the substrate;
- and
- interconnecting the number of the plurality of power modules together.
A system comprising:
- a first power module comprising:
- a substrate;
- a plurality of inductors stacked over the substrate, the plurality of inductors comprising:
- a first inductor comprising a common core and a first winding around the common core, and
- a second inductor comprising a second winding around the common core, wherein the second winding is 1800 out of phase with the first winding, and
- a voltage regulator comprising a first switch and a second switch, wherein each of a first switch and a second switch of the voltage regulator are stacked directly over a top side of the plurality of inductors such that the plurality of inductors are positioned directly between the voltage regulator and a substrate, wherein the plurality of inductors are stacked directly over the substrate;
- and
- a second power module connected to the first power module in parallel, wherein the first power module and the second power module together provide a determined amount of power to a powered system.
A power conversion system for providing a predetermined power to a powered system, the system comprising:
- a power module comprising:
- a substrate;
- an inductor stacked over the substrate, wherein the inductor comprises a top side and a bottom side, and
- a voltage regulator comprising a first switch and a second switch, wherein the voltage regulator is stacked over a top side of the inductor such that the inductor is positioned directly between the voltage regulator and the substrate, wherein the first switch of the voltage regulator is positioned over a first lateral side of the inductor, and wherein the second switch of the voltage regulator is positioned over a second lateral side opposite the first lateral side of the inductor;
- and
- a controller connected to the power module, wherein the controller is operative to:
