Claim 6:
7. A method, comprising:
coupling, by a power converter circuit during a first portion of a first cycle of a particular switching sequence, an input power supply node to a switch node coupled to a regulated power supply node via an inductor;
coupling, by the power converter circuit 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;
coupling, by the power converter circuit during a third portion of the first cycle of the particular switching sequence, the switch node to ground supply node; and
adjusting, by the power converter circuit, 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.
