Claim 2:
3. The DC-DC converter according to claim 2, wherein the SC circuit further comprises a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a sixth switch, and a seventh switch, wherein:
a first end of the first switch is coupled to the ground end, a first end of the second switch is coupled to the voltage output end, a second end of the first switch is coupled to a first end of the third capacitor, and a second end of the second switch is coupled to the first end of the third capacitor;
a first end of the third switch is coupled to the ground end, a first end of the fourth switch is coupled to a second end of the first capacitor, a second end of the third switch is coupled to a first end of the fourth capacitor, and a second end of the fourth switch is coupled to the first end of the fourth capacitor;
a second end of the third capacitor is coupled to a first end of the fifth switch, a second end of the fifth switch is coupled to the voltage output end, a second end of the fourth capacitor is coupled to a first end of the sixth switch, and a second end of the sixth switch is coupled to the first end of the fifth switch;
a first end of the seventh switch is coupled to the voltage input end, and a second end of the seventh switch is coupled to the second end of the fourth capacitor; and
a first end of the first capacitor is coupled to the voltage input end, the second end of the first capacitor is coupled to a first end of the second capacitor, and a second end of the second capacitor is coupled to the ground end; and
when the first switch, the fourth switch, the fifth switch, and the seventh switch are turned on, and the second switch, the third switch, and the sixth switch are turned off, the third capacitor discharges energy, and the fourth capacitor stores energy; and
when the first switch, the fourth switch, the fifth switch, and the seventh switch are turned off, and the second switch, the third switch, and the sixth switch are turned on, the third capacitor stores energy, and the fourth capacitor discharges energy.
