Classification: CPC H  G | IPC G  H

Claim 13:
14. An apparatus, comprising:
a load circuit coupled to a regulated power supply node; and
a power converter circuit that includes a switch node coupled to the regulated power supply node via an inductor, wherein the power converter circuit is configured to:
couple, during a first portion of a first cycle of a particular switching sequence, an input power supply node to the switch node;
couple, during a second portion of the first cycle of the particular switching sequence, a capacitor between an input power supply node and the switch node;
couple, during a third portion of the first cycle of the particular switching sequence, the switch node to ground supply node; and
adjust a duration of the first portion of the first cycle of the particular switching sequence based on a voltage level of the input power supply node, a voltage level of the regulated power supply node, a value of the inductor, and respective durations of second and third portions of the first cycle.
