1. A high power density power circuit to convert an input voltage to a regulated output voltage, the high power density power circuit comprising:
a first capacitor, a second capacitor, and an inductor to be coupled to the first and second capacitor via a shared node; and
a plurality of switches to alternately arrange the inductor and the first capacitor and second capacitor into a first configuration or a second configuration, the first and the second configurations to include the shared node,
wherein, in the first configuration, the second capacitor is to discharge at a rate that is based at least in part on the inductor, and
wherein, in the second configuration, the first capacitor is to discharge at a rate that is based at least in part on the inductor.
