Abstract
A hierarchical, scalable power delivery system is disclosed. The power delivery system includes a first level of power converter circuitry configured to generate one or more first level regulated supply voltages, and a second level of power converter circuitry configured to generate one or more second level regulated supply voltages. The first level of power converter circuitry receives an input supply voltage, while the second level power converter circuitry receives the one or more first level supply voltages. The second level power converter circuitry is configured to provide the second level regulated supply voltages to a computing element configured to operate as a single, logical computer system, the computing element being configured to operate in a number of power configurations having differing numbers of load circuits. Different portions of the hierarchical power delivery system may be selectively enabled for corresponding ones of the power configurations of the computing element.
