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 couple the switch node to a capacitor for different periods of time using respective different subsets of the multiple devices. A control circuit may modify active times of control signals coupled to the multiple devices based on voltage samples of the switch node in order to adjust the durations of the different periods of time.
