POWER SOURCE CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/151375
Kind Code:
A1
Abstract:
A power source circuit and an electronic device. The power source circuit (100) comprises: a voltage conversion circuit (110), an input end of which is connected to a power-supply power source; a first gating circuit (120), wherein one end of the first gating circuit (120) is connected to an output end of the voltage conversion circuit (110), and the other end of the first gating circuit (120) is connected to a battery; a second gating circuit (130), wherein one end of the second gating circuit (130) is connected to the output end of the voltage conversion circuit (110) by means of an inductor (L), the other end of the second gating circuit (130) is connected to the battery, and one end of the second gating circuit (130) is further connected to a load; and a control circuit (140), which is used for controlling the power-supply power source to quickly charge the battery by means of the voltage conversion circuit (110) when the first gating circuit (120) is in a switched-on state, and controlling the power-supply power source to perform pre-charging or constant-voltage charging on the battery by means of the voltage conversion circuit (110) or controlling the battery to supply power to the load when the second gating circuit (130) is in a switched-on state.
