Abstract
Certain aspects of the present disclosure generally relate to electronic circuits and, more particularly, to a power supply circuit and techniques for voltage regulation. One example method for voltage regulation is performed by a switched-mode power supply (SMPS). The method generally includes charging a first capacitive element during a first discharge phase of the SMPS having a first voltage rail and a second voltage rail, the first voltage rail being separate from the second voltage rail. Charging the first capacitive element may include directing a first current to flow from the second voltage rail to a reference potential node through the first capacitive element. In some aspects, the method also includes generating an output voltage at the output node during a first charge phase by directing a second current to flow from the first voltage rail to an inductive element of the SMPS through the first capacitive element.
