In one embodiment of the present invention, a system includes a power stage component operable to generate an output voltage from a power source and to provide the output voltage to an electrical device. The power stage component is capable of operating in a plurality of modes depending on a level of the power source. An adaptive mode change component, coupled to the power stage, is operable to track at least one variation which affects the voltage across the electrical device and to generate at least one control signal for changing among the plurality of operating modes of the power stage component in response to the tracking.
