Abstract
Illustrated are a switched-capacitor DC-DC convertor and a control method thereof. The switched-capacitor DC-DC convertor includes a switched-capacitor circuit, a latched comparator and a clock generating module. The switched-capacitor circuit converts an input voltage into an output voltage through a phase switching operation. The latched comparator receives a clock signal, and compares the output voltage and a reference voltage according to the clock signal, to generate the control signal, which triggers a phase switching operation of the switched-capacitor circuit. The clock generating module generates the clock signal, and adjusts a frequency of the clock signal according to variation of the control signal.
