Abstract:
(EN) Disclosed are a power supply circuit, an electronic assembly, a mobile terminal, and a power supply control method. The circuit comprises n capacitors, m power branches, and a control chip. The m power branches comprise at least one first type power branch and at least one second type power branch. The first type power branch comprises a pre-boost topology structure and an open-loop topology structure connected in series with the pre-boost topology structure. The pre-boost topology structure is connected with the control chip. The pre-boost topology structure comprises a direct state and a closed-loop state. The control chip is used for controlling the pre-boost topology structure to switch between the direct state and the closed-loop state according to an output voltage of a power supply to enable the pre-boost topology structure to pre-adjust the output voltage of the power supply and output a voltage range required by the open-loop topology structure. The problem of a narrow range of an input voltage in the related art is solved.
(FR) L'invention concerne un circuit d'alimentation électrique, un ensemble électronique, un terminal mobile et un procédé de commande d'alimentation électrique. Le circuit comprend n condensateurs, m branches de puissance et une puce de commande. Les m branches de puissance comprennent au moins une branche de puissance de premier type et au moins une branche de puissance de second type. La branche de puissance de premier type comprend une structure de topologie de pré-amplification et une structure de topologie de boucle ouverte connectée en série avec la structure de topologie de pré-amplification. La structure de topologie de pré-amplification est connectée à la puce de commande. La structure de topologie de pré-amplification comprend un état direct et un état de boucle fermée. La puce de commande est utilisée pour commander la structure de topologie de pré-amplification pour commuter entre l'état direct et l'état de boucle fermée en fonction d'une tension de sortie d'une alimentation électrique pour permettre à la structure de topologie de pré-amplification d'ajuster au préalable la tension de sortie de l'alimentation électrique et de délivrer une plage de tension requise par la structure de topologie de boucle ouverte. Le problème d'une plage étroite d'une tension d'entrée dans l'état de la technique associé est résolu.
