    Abstract: A reconfigurable multi-phase power converter is disclosed. An apparatus comprises a first primary power converter configured to generate a first regulated supply voltage to a first regulated supply voltage node and a second primary power converter configured to generate a second regulated supply voltage to a second regulated supply voltage node. The apparatus further includes N secondary power converters, wherein N is an integer value of one or more, and a multiplexer circuit configured to select the at least one of the N secondary power converters to provide an output current to one of the first or second regulated supply voltage nodes.

    Abstract: A power management circuit included in a computer system regulates a voltage level of a power supply node used by other circuits in the computer system. The power management circuit includes a control circuit and multiple phase circuits coupled to the regulated power supply node via corresponding inductors. The control circuit selectively activates particular ones of the multiple phase circuits allowing them source respective currents to the regulated power supply node. The control circuit also selectively activates particular ones of other phase circuits that are external to the power management circuit and coupled to the regulated power supply node via their own corresponding inductors. Once activated, the external phase circuits source respective currents to the regulated power supply node via their corresponding inductors.

    Abstract: A power converter circuit that includes two flying capacitors, is coupled to a regulated power supply node in a computer system. The power converter circuit magnetizes an inductor using the two flying capacitors during a first phase. During a second phase, the power converter circuit charges one of the flying capacitors, de-magnetizes the inductor, and transfers charge to the regulated power supply node. The power converter circuit magnetizes the inductor using the flying capacitors, and transfers charge to the regulated power supply node during a third phase. During a fourth phase, the power converter circuit again de-magnetizes the inductor, charges the one of the flying capacitors, and transfers charge to the regulated power supply node.
