Abstract
A power supply circuit that converts a single input voltage to a multi-stage output voltage, includes: one or more switched capacitors capable of transforming the input voltage at one or more transformation ratios and applying a lower transformation ratio as the input voltage increases; and a regulator that adjusts an intermediate voltage based on an output power from the switched capacitor to the output voltage.

A power supply circuit that converts a single input voltage to a multi-stage output voltage, comprising:
- one or more switched capacitors capable of transforming the input voltage at one or more transformation ratios and applying a lower transformation ratio as the input voltage increases;
- and
- one or more regulators that adjust an intermediate voltage based on an output power from each of the switched capacitors to the output voltage.
