Abstract: Voltage dividing circuitry is provided for use in a voltage converter for converting at least one input Direct Current, DC voltage to a plurality of output DC voltages. The voltage dividing circuitry including a voltage input port to receive an input DC voltage and an inductor having an input-side switch node and an output-side switch node. The output side switch node is connectable to one of a plurality of voltage output ports to supply a converted value of the input DC voltage as an output DC voltage. The flying capacitor interface has a plurality of switching elements and at least one flying capacitor, to divide the input DC voltage to provide a predetermined fixed ratio of the input DC voltage at the input-side switch node of the inductor. A voltage converter and a power management integrated circuit having the voltage dividing circuitry are also provided.

Abstract: An electronic device may include a harvester device to receive an alternative power from an alternative power source. An electronic device may also include a cold-start device to provide an additional power derived from the alternative power source. The harvester device may receive the additional power from the cold-start device, and combine the alternative power and the additional power to at least a specific level.
