Claim:
1. An apparatus comprising: a first node to receive an input voltage; a second node to provide an output voltage; circuit lanes coupled to the first and second nodes, each of the circuit lanes including switches coupled between the first and second nodes; and a controller to selectively place at least one circuit lane among the circuit lanes in an activated state to cause the at least one circuit lane to control the switches in order to adjust an amount of charge provided from a capacitor network to the output node based on a toggling frequency of a comparator output signal generated based on a comparison between a value of a reference voltage and a value of a feedback voltage generated from a value of the output voltage, wherein the amount of charge provided from the capacitor network to the output node is proportional to a number of activated circuit lanes among the circuit lanes.
