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.

Abstract: A switched capacitor voltage regulator (SCVR) design, such as a continuous capacitive voltage regulator (C2VR) design, may use capacitors and switches to provide improved cost and space efficiencies. A remote sensing circuit may be used to improve C2VR performance. By adding a remote sensing circuit to the regulation feedback loop within the C2VR circuit design, the C2VR circuit may provide improved accuracy in voltage regulation, such as by providing a correction based on the voltage error between the remote-sensed voltage and the reference target. The remote sensing circuit may also provide transient information for under-voltage detection at an output terminal. This detected transient may become an alternating current (AC) portion of the under-voltage detection threshold, which improves the ability of the C2VR circuit to provide early detection for any under-voltage fault.
