Abstract: Interposer printed circuit boards for power modules and associated methods are disclosed. In at least one illustrative embodiment, a printed circuit board assembly may comprise a printed circuit board, an electrical component mounted on a surface of the printed circuit board, and an interposer printed circuit board mounted on the surface of the printed circuit board. The interposer printed circuit board may comprise a first signal path to transmit a first electrical signal and a second signal path to transmit a second electrical signal that is different from the first electrical signal. The interposer printed circuit board may be configured to provide a standoff to prevent the electrical component from contacting a motherboard when the printed circuit board assembly is mounted to the motherboard.

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.

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: A DC-to-DC power converter includes a reference voltage generator and a tangible, non-transitory, computer-readable memory. The memory stores a temperature coefficient, and the temperature coefficient is based upon a temperature response of said reference voltage generator over a range of temperatures. The DC-to-DC power converter also includes a controller coupled to the reference voltage generator and the memory and operable to retrieve the temperature coefficient from the memory, and adjust an output voltage of the DC-to-DC power converter based upon the temperature coefficient.
