Regulated power converter with adiabatic charge pump

Abstract:

A power converter circuit included in a computer system may include an adiabatic charge pump which includes multiple capacitors different numbers of which are used to charge and discharge a switch node coupled to regulated power supply node via an inductor. A control circuit may control the dividing ratio of the charge pump circuit as well as determine respective durations of when the charge pump circuit is charging and discharging the switch node.
