Abstract: Embodiments herein describe a voltage regulator with at least one power stage (or phase) that includes circuitry for providing an efficiency mode for low power situations. For example, when an output voltage and current of the power stage is below a threshold, the voltage regulator can switch to the efficiency mode (e.g., a high efficiency mode (HEM)). When in the efficiency mode, the power stage can use a first, lower input voltage to perform pulse width modulation (PWM). However, when in a high power mode, the power stage can use a second, higher input voltage to PWM. For example, the power stage can include one or more switches for switching between the first and second input voltages to use in the different modes of operation.
