1. A method of manufacturing a power module on a substrate, comprising:
- providing power conversion circuitry, including;
providing a magnetic device having a magnetic core on said substrate,placing a shielding structure with a baffle over said magnetic core to create a chamber thereabout, andproviding at least one switch on said substrate; and
depositing an encapsulant about said power conversion circuitry, said shielding structure limiting said encapsulant entering said chamber and said baffle directing said encapsulant away from said magnetic core thereby limiting an amount of said encapsulant that contacts said magnetic core within said chamber.

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.
