  • Publication number: 20240203630
    Abstract: The disclosure relates to power modules that include elevated inductors with capacitors disposed under the inductors. In one aspect, a power module includes a first circuit board having a first surface and a second surface opposite the first surface. One or more inductors are mounted on the first surface. Each of the one or more inductors includes a top surface and a bottom surface opposite the top surface and that faces the first surface of the first circuit board. Each inductor is elevated above the first surface of the first circuit board such that at least a portion of the bottom surface of the inductor does not contact the first surface of the first circuit board. The first circuit board includes capacitors arranged in an area below the portion of the bottom surface of the inductor that does not contact the first surface of the first circuit board.
