  • DISTRIBUTED POWER MANAGEMENT WITH SEPARATE PEAK AND AVERAGE POWER PATHS
    Publication number: 20260142570
    Abstract: A power management circuit for a computer system is disclosed. The power management circuit includes a power storage circuit, a first power converter circuit, and a second power converter circuit. The first power converter circuit sources a current to a regulated power supply node via a first inductor under average load conditions using a voltage level of an input power supply node. During high-load transient conditions, the second power converter circuit provides additional current to the regulated power supply node via a second inductor using a voltage generated by the power storage circuit.
    Type: Application
