Abstract: A device for generating a plurality of output voltages from a single input energy supply source is described. The device includes a switched capacitor voltage converter that provides each of the output voltages having different supply ratios. The supply ratio is defined as a function of the input voltage provided to the switched capacitor voltage converter by the energy supply source. The switched capacitor voltage converter includes a plurality of capacitors selectively coupled to a plurality of switches that dynamically configure the capacitors into a plurality of stacked configurations. Switching between the plurality of stacked configurations may be controlled based on predetermined criteria.
