Abstract
A power module located on a substrate. In one embodiment, the power module includes power conversion circuitry with a magnetic device and at least one switch. The magnetic device includes a magnetic core with a shielding structure located about the magnetic core configured to create a chamber thereabout. The power module also includes an encapsulant about the power conversion circuitry. The shielding structure is configured to limit the encapsulant entering the chamber thereby allowing the encapsulant to surround a portion of the magnetic core within the chamber.

A power module located on a substrate, comprising:
- power conversion circuitry, including:
- a magnetic device having a magnetic core with a shielding structure having a baffle located about said magnetic core configured to create a chamber thereabout, and
- at least one switch;
- and
- an encapsulant about said power conversion circuitry, said shielding structure configured to limit said encapsulant entering said chamber and said baffle configured to direct said encapsulant away from said magnetic core thereby allowing said encapsulant to surround a portion of said magnetic core within said chamber.
