Abstract: Some embodiments provide a multi-phase DC/DC switching converter in which each of the phases are controlled using a common comparator for comparing an output voltage of the switching converter and a reference voltage, with in some embodiments each of the phases including a bypass switch for coupling ends of an output inductor of the switching converter. Some embodiments provide a multi-phase DC/DC switching converter in which some of the phases are operated with clock signals having frequencies different than clock signals used for operating others of the phases. Some embodiments provide a multi-phase DC/DC switching converter in which some of the phases include inductors having inductances different than inductances for inductors of others of the phases.

Abstract: A scalable switching regulator architecture may include an integrated inductor. The integrated inductor may include vias or pillars in a multi-layer substrate, with selected vias coupled at one end by a redistribution layer of the multi-layer substrate and, variously, coupled at another end by a metal layer of a silicon integrated circuit chip or by a further redistribution layer of the multi-layer substrate. The vias may be coupled to the silicon integrated circuit chip by micro-balls, with the vias and micro-balls arranged in arrays.

Abstract: Dedicated circuitry may monitor a processor supply voltage and provide additional power on a temporary nano-second scale basis to the processor when the supply voltage drops below predetermined levels. This may be done without explicit knowledge of a commanded supply voltage level for the processor.

Abstract: Circuitry may monitor a processor supply voltage and pull power from the processor supply on a temporary basis when the supply voltage rises above predetermined levels. In some embodiments this may be done without explicit knowledge of a commanded supply voltage level for the processor.

Abstract: A fault detection circuit may be used to determine if voltage supplied by a voltage regulator as power to sequential logic circuitry falls below a minimum voltage expected to be required by the sequential logic circuitry for proper operation. Information regarding voltage levels supplied to the sequential logic circuitry prior to such an occurrence may be written to a memory, for example to allow for further analysis.

Abstract: A transimpedance regulator may include a switched capacitor converter, with a current input and a regulated voltage output. A DC-DC switching converter with an inductive component may be used as a current source for the switched capacitor converter. In some embodiments the DC-DC switching converter with an inductive component may be operated in a manner expected to provide optimum power efficiency, with the switching capacitor converter providing a desired regulated voltage output.

Abstract: A DC-DC switching converter with an LC output filter has a switched capacitor converter providing the capacitance of the output filter. The switched capacitor converter may be a multi-phase switched capacitor converter. Topology of connections between capacitors of the multi-phase switched capacitor converter may be dependent on phases of clock signal(s) provided to the multi-phase switched capacitor converter. The switched capacitor converter may rely on parasitic inductances, or include discrete inductors, in series between connected capacitors to allow for adiabatic or near adiabatic voltage conversion.
