Abstract

The invention discloses a charging adapter, a terminal and a charging control method, and aims to solve the problem that the charging current is difficult to increase in the prior art. The charging adapter comprises an alternating-current transformer, a direct-current transformer, an external charging chip and a micro controller. The output end of the alternating-current transformer is connected with the direct-current transformer and the external charging chip. The micro controller is used for causing the alternating-current transformer to provide direct-current output and causing the direct-current transformer to carry out direct current transformation and output after the charging adapter and the terminal are effectively connected, and used for causing the external charging chip to charge the terminal after handshake connection between the charging adapter and the terminal is established. By adopting the charging adapter provided by the embodiment of the invention, the charging current can be increased, and the charging efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a charging adapter, a terminal, and a charging control method. Background technique [0002] Most of the current mobile terminals are charged by connecting the charging adapter through the USB interface, such as figure 1 As shown, the charging principle is: when the charging adapter 11 is connected to the mobile terminal 12, the transformer 111 in the charging adapter converts the high-voltage 220V alternating current into 5V direct current, and outputs it to the mobile terminal 12 through the USB interface, and the built-in charging of the mobile terminal 12 The chip 121 then performs DC transformation on the 5V DC power, and finally inputs it into the battery 122 with a suitable voltage and current intensity. At present, the power consumption of mobile terminals is increasing, and the battery capacity is also increasing. The problems of charging heat and slow ch...
