Abstract

A switched capacitor converter circuit includes: a conversion capacitor; an output capacitor; and switches configured to switch the coupling configurations of the conversion capacitor and the output capacitor according to a level of the first power supply voltage of the switched capacitor converter circuit, to generate the second power supply voltage at the output capacitor according to the first power supply voltage. The second power supply voltage provides power to control the power converter circuit. When the first power supply voltage is higher than a high threshold, the switched capacitor converter circuit controls the second power supply voltage to be lower than the first power supply voltage. When the first power supply voltage is lower than a low threshold, the switched capacitor converter circuit controls the second power supply voltage to be higher than the first power supply voltage.
