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.

An apparatus that includes an interposer, first power connectors that are disposed on a first surface and that receive respective power inputs from one or more power sources, second power connectors that are disposed on the second surface and that receive a respective third power connecter of an integrated circuit when the integrated circuit is mounted on the second surface of the interposer, a plurality of switches formed within the interposer, control circuitry formed within the interposer, and a sequencer circuit coupled to the control input of the control circuitry and that generates a different values for a control input signal that causes the control logic of the control circuitry to generate a corresponding set of switch signals, and the plurality of different values for the control input signal are generated according to a predefined sequence to provide power to the integrated circuit according to power up sequence.

Power sequencing in an active silicon interposer

An electromagnetic interference ('EMI') sheet attenuator includes a planar conductive layer, a first flexible substrate and a second flexible substrate. The first flexible substrate overlies the metal backing layer and including a conductive pattern on a surface of the first flexible substrate. The second flexible substrate overlies the first flexible substrate and also includes the conductive pattern. The conductive pattern on the second flexible substrate is aligned with the conductive pattern on the first flexible substrate.

An apparatus that includes first and second parallel converter branches, each parallel converter branch including an input node, N output nodes, a plurality of switches, a converter output node, and control logic. The control logic generates a first set of switch signals to control the switches of the first parallel converter branch and a second set of switch signals to control the second parallel converter branch, the first set switch signals and the second set of switch signals having respective duty cycles to cause each of the first and second parallel converter branches to output the DC output voltage on each of the N output nodes.

Multi-phase converter

At least one aspect is directed to a power supply. The power supply includes one or more unregulated voltage converters. Each unregulated voltage converter includes a switched block producing an output voltage across its output terminals. The power supply includes a voltage supply input coupled to at least one of the unregulated voltage converters, and an unregulated voltage bus coupled to at least one of the unregulated voltage converters. The power supply includes a voltage regulator coupled to the unregulated voltage bus and producing a regulated voltage across its output terminals. The output terminals of the voltage regulator are connected in parallel to the output terminals of at least one of the unregulated voltage converters. This can produce a regulated output voltage across a pair of power supply output terminals.
