Abstract

A power converter circuit included in a computer system may charge and discharge a switch node coupled to a regulated power supply node via an inductor. The power converter circuit may generate a reference clock signal using a system clock signal and a voltage level of the switch node. The reference clock signal may be used to initiate a charge cycle, whose duration may be based on generated ramp signals.
