Devices and methods provide a voltage regulating device including voltage supply circuitry configured to receive a first voltage, generate at least a second voltage based on the first voltage, and output an output voltage, the output voltage being one of the first voltage and the second voltage based on a voltage selection signal; regulator circuitry configured to switch between the output voltage and a reference potential based on a control signal; and control circuitry configured to generate the control signal, the control signal having a first duty cycle if the output voltage is the first voltage and a second duty cycle if the output voltage is the second voltage, the control circuitry configured to adjust the second duty cycle based on, at least in part, a droop voltage in the regulator circuitry.
