Abstract
A method of manufacturing a power module on a substrate. In one embodiment, the method includes providing power conversion circuitry including providing a magnetic device having a magnetic core and at least one switch on the substrate. The method also includes placing a shielding structure over the magnetic core to create a chamber thereabout. The method also includes depositing an encapsulant about the power conversion circuitry. The shielding structure limits the encapsulant entering the chamber thereby allowing the encapsulant to surround a portion of the magnetic core within the chamber.
