Claim 4:
5. The DC-DC converter according to claim 4, wherein:
when the output voltage at the voltage output end is lower than target voltage, on duration of the eighth switch is prolonged, so that the SC circuit reaches a stable state;
when the output voltage at the voltage output end is higher than the target voltage, on duration of the ninth switch is prolonged, so that the SC circuit reaches a stable state; and
when the SC circuit reaches a stable state, voltage between the two ends of the first capacitor is twice the output voltage at the voltage output end, and voltage between the two ends of the second capacitor is a difference between the input voltage and the voltage between the two ends of the first capacitor.
