Title:
CHARGING CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/207706
Kind Code:
A1
Abstract:
A charging circuit and an electronic device, relating to the technical field of electronics, and capable of improving the power of high power fast charging. The charging circuit comprises: at least two direct current-direct current (DC-DC) conversion circuits which are coupled between a power supply end and a charging end. The power supply end is coupled to a charger, and the charging end is used for coupling a battery; a voltage input end of each DC-DC conversion circuit is coupled to the power supply end; a voltage output end of the DC-DC conversion circuit is coupled to the charging end; the at least two DC-DC conversion circuits comprise a first DC-DC conversion circuit and a second DC-DC conversion circuit; the first DC-DC conversion circuit is configured to perform voltage conversion on a voltage of the power supply end so as to output a first charging signal to the battery; the second DC-DC conversion circuit is configured to perform voltage conversion on the voltage of the power supply end so as to output a second charging signal to the battery; the first DC-DC conversion circuit comprises a voltage-regulatable DC conversion circuit, and the second DC-DC conversion circuit comprises a non-voltage-regulatable DC conversion circuit.
