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.

Abstract: A single inductor multiple output DC-to-DC converter may be configured as a buck-boost converter. The converter may include an inductor, a plurality of switches coupled to the inductor to control energizing and deenergizing phases of the inductor, and a plurality of output rails. Each of the plurality of output rails may include at least one switch, which is configured to connect the output rail to the inductor of the buck-boost converter. Depending on the energizing and deenergizing patterns of the inductor, and the state of the one or more switches, the various output rails may be supplied with a plurality of different output voltages and / or output currents. Any of a plurality of regulating strategies may be utilized to further control the output voltages and / or the output currents.
