Abstract
Various embodiments provide a voltage regulator circuit with automatic phase shedding. A control circuit may control first transitions of a power state of the voltage regulator based on an average current draw of the voltage regulator. The control circuit may further control second transitions of the power state of the voltage regulator based on a voltage droop of the output voltage and/or a peak current draw of the voltage regulator. The first transitions may be performed synchronously, and the second transitions may be performed asynchronously. Other embodiments may be described and claimed.
