Abstract

Methods and electronic devices are disclosed for supplying a load with an input voltage including determining a level of a supply voltage. The method includes enabling a voltage step-down unit while disabling a voltage step-up unit when the supply voltage exceeds a first threshold voltage. The method includes enabling a voltage step-up unit while disabling a voltage step-down unit when the supply voltage is below a second threshold voltage. The electronic device includes a voltage step-up unit for stepping up the supply voltage below a first threshold, a voltage step-down unit for stepping down the supply voltage above a second threshold, and a switching unit coupled to the voltage step-up unit and the voltage step-down unit. The switching unit is configured to at least one of enable and bypass at least one of the voltage step-down unit and the voltage step-up unit based on the level of the supply voltage.
