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.

Abstract: A power converter circuit includes a switch circuit coupled to an input power supply node and a regulated power supply node and a control circuit. The switch circuit includes an inductor, a first capacitor, a second capacitor, a third capacitor, and a plurality of switch devices. The switch circuit magnetizes the inductor using the first capacitor during a first phase and to de-magnetize the inductor using the second capacitor, charges the first capacitor using a voltage level of an input power supply node, and exchanges a first amount of charge with the regulated power supply node during a second phase. The switch circuit magnetizes the inductor using the first capacitor during a third phase, and de-magnetizes the inductor, charges the first capacitor using the voltage level of the input power supply, and exchanges a second amount of charge with the regulated power supply node during a fourth phase.
