Abstract:
The switch circuit comprises a first switch, a second switch, a third switch, a forth switch, a fifth switch, a sixth switch and a seventh switch. The first switch couples the voltage input terminal to one terminal of a flying capacitor. The second switch couples one terminal of the flying capacitor to one terminal of the output capacitor. The third switch couples one terminal of the flying capacitor to a common terminal. The fourth switch couples the other terminal of the flying capacitor to one terminal of the output capacitor. The fifth switch couples one terminal of the output capacitor to a positive voltage output terminal. The sixth switch couples the other terminal of the flying capacitor to the common terminal. The seventh switch couples the other terminal of the flying capacitor to a negative voltage output terminal.
