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, using different subsets of the multiple devices, charge a capacitor for a first period of time and then couple the switch node to the capacitor for a second period of time. A control circuit may sense, using a common circuit, different characteristics of a current through the inductor during respective operation modes, and adjust the first and second periods of time based on the different characteristics of the current and a current operation mode.
