Abstract
A magnetic device, method of manufacture therefor and a power supply employing the magnetic device. In one embodiment, the magnetic device includes a metal substrate and a first dielectric layer formed over the metal substrate. The magnetic device further includes a first conductive layer formed over only a portion of the dielectric layer and a magnetic core mounted proximate the first conductive layer adapted to impart a desired magnetic property thereto.
