The invention discloses power conversion with power balance in a device. An apparatus is provided that includes a power string and a step-down circuit. A power supply is connected in series to provide a first voltage rail at a first voltage, and the power supply string is divided into power supply segments. The step-down circuit is electrically configured to provide a second voltage rail at a second, lower voltage. The step-down circuit includes a control circuit configured to monitor a state of charge of the power supply segments, and to control selection of one of the power supply segments to deliver an output, by which the second voltage rail is provided, based on the state of charge. One or more first electronic components are electrically coupled to the first voltage rail and are designed to operate at a first voltage. And one or more second electronic components electrically coupled to the second voltage rail and designed to operate at a second voltage.
