    Abstract: At least one embodiment of a power supply includes a printed circuit board formed from a plurality of double-sided laminates and a plurality of thermally conductive, electrically insulating pre-preg sheets interleaved with the plurality of double-sided laminates. Each double-sided laminate illustratively includes an electrically insulating core, a first patterned layer of electrically conductive material arranged on a first side of the electrically insulating core, and a second patterned layer of electrically conductive material arranged on a second side of the electrically insulating core opposite the first side. The printed circuit board illustratively further includes a thermally conductive, electrically insulating additive resin filling spaces between the electrically conductive material in both the first and second patterned layers of each of the plurality of double-sided laminates, such that the electrically conductive material and the additive resin together form planar surfaces that contact the plurality of pre-preg sheets.

    Abstract: An integrated magnetic assembly includes a magnetic core having a first component and a second component. The first component includes a first face and a winding leg extending from the first face. The winding leg includes a top face spaced from and oriented generally parallel to the first face. The second component is coupled to the first component and has a second face facing the first face. The second component further includes a third face recessed from and oriented generally parallel to the second face and a recess sidewall extending between the second face and the third face. The integrated magnetic assembly further includes an input winding and an output winding each inductively coupled to the magnetic core. The third face and the recess sidewall define a recess within the second face. Additionally, a gap is defined between the top face and the third face.
