Abstract: A power converter circuit that includes a switch node coupled to a regulated power supply node via an inductor may, during a charge cycle, source current to the switch node, and source a bypass current to the regulated power supply node using a regulator control signal. A control circuit may initiate the charge cycle using a first reference voltage level and a sensed inductor current, and generate the regulator control signal using a second reference voltage level and a voltage level of the regulated power supply node.
