Abstract: This application provides a charging/discharging circuit and an electronic device, and relates to the field of electronic technologies, to improve utilization of a switched capacitor circuit and reduce an area of the charging/discharging circuit. The charging/discharging circuit provided in this application includes a switched capacitor (SC) circuit, configured to charge/discharge a battery. The switched capacitor (SC) circuit includes a first end, configured to receive an input power supply voltage; a second end, configured to: provide a charging voltage for a battery in a charging process, and receive a discharging voltage released by the battery in a discharging process; and a third end, configured to provide an output voltage, where the output voltage is a direct current voltage or a pulse width modulation (PWM) voltage.

Abstract: Examples direct current-direct current (DC-DC) converter are described. One example DC-DC converter includes three ports and a switch capacitor (SC) circuit. A first port and a second port are input and output ports, and a third port is grounded. The SC circuit includes three capacitors and eight switching transistors. A connection relationship between the three capacitors and eight switching transistors determines that an end of one capacitor in the three capacitors is grounded, and the other two capacitors are connected between the switching transistors.
