VOLTAGE REGULATOR MODE OPERATIONS

Abstract: in an example, a computing device includes a voltage regulator having a voltage regulator controller, a first power stage circuit, and a second power stage circuit. when a control signal indicates that the voltage regulator is to operate in a single-phase mode, the first power stage circuit supplies a first current to a hardware processor and the second power stage circuit does not supply a second current to the hardware processor, where a maximum output current of the first power stage circuit is lower than a maximum output current of the second power stage circuit. when the control signal indicates that the voltage regulator is to operate in a multi-phase mode, the first power stage circuit supplies the first current and the second power stage circuit supplies the second current to the hardware processor.
