Abstract

The invention provides a charger outputting different voltages in a self-adaptation mode and an implementation method of the charger. The charger comprises a charging protocol recognition unit and a charging control unit, wherein the charging protocol recognition unit is used for detecting a terminal detecting port, recognizing a charging protocol matched with the mobile terminal and outputting a corresponding feedback signal; the charging control unit is used for feeding back a signal and controlling the output of the voltage regulated in the matched charging protocol to the terminal detecting port. The method includes the steps that the terminal detecting port of the mobile terminal is detected, the charging protocol matched with the mobile terminal is determined, and the current output voltage is changed to the voltage regulated in the charging protocol and then output to the terminal detecting port. According to the embodiment of the charger outputting different voltages in the self-adaptation mode and the implementation method of the charger, the charger can output multiple voltages in the self-adaptation mode, and the requirement of different terminals for voltage can be met; charging voltage can be boosted, large-current charging is guaranteed, EMC is reduced, and the requirement for peripheral components can also be lowered.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a charger capable of adaptively outputting different voltages and an implementation method thereof. Background technique [0002] Generally speaking, mobile terminals (such as mobile phones and tablet computers) use batteries as power sources. Of course, these batteries can usually be recharged and used. When the battery power in the mobile terminal is used up, it can be used after charging. Usually, the purpose of charging can be achieved by connecting the power terminal and the ground terminal of the charger to the positive pole and the negative pole of the battery on the mobile terminal respectively through a special connector provided on the mobile terminal. In the prior art, the output voltage of the above-mentioned charger is fixed at 5V, which cannot output corresponding different voltage values ​​according to the needs of each mobile terminal. Contents of the inve...
