Original Abstract Submitted

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.
