Abstract

A voltage regulator circuit included in a computer system may include multiple devices and a switch node coupled to a regulated power supply node via an inductor. The voltage regulator circuit may charge a capacitor using an input power supply signal, and couple the capacitor to the switch node using respective subsets of the multiple devices, which are selected based on one or more control signals. A control circuit may generate the one or more control signals based on a particular switching sequence, which is selected based on a ratio of a voltage level of the regulated power supply node and a voltage level input power supply signal.
