Apparatus includes a first connection to a battery; a second connection to a component; a first path between the first and second connections including a non-upconverting voltage regulator and being absent of a voltage upconverter; a second path between the first and second connections including a voltage upconverter; and a controller. The controller is configured to determine a minimum operating voltage of the component; to determine whether a voltage provided at the first connection meets a predetermined relationship with respect to the minimum operating voltage of the component; and on a positive determination, to enable the first path and disable the second path, and on a negative determination, to disable the first path and enable the second path.
