Abstract

The invention provides a voltage sampling control method, a voltage sampling control circuit and an adapter. The method comprises the steps that the adapter receives an output voltage adjusting instruction sent by a mobile terminal; according to the output voltage adjusting instruction, the target output voltage of the adapter is determined; on the basis of the preset corresponding relation, a target voltage sampling ratio corresponding to the target output voltage is determined; the voltage sampling ratio of the output voltage sampling circuit is adjusted into the target voltage sampling ratio, wherein the voltage sampling ratio is the ratio of the sampling voltage of the output voltage sampling circuit to the output voltage of the adapter. The application range of the adapter can be widened.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a voltage sampling control method, a voltage sampling control circuit and an adapter. Background technique [0002] With the development of the communication technology, the functions of the mobile terminal become more and more abundant, and the operating load of the mobile terminal also increases accordingly, resulting in shorter and shorter standby time of the mobile terminal. At the same time, the design of mobile terminals tends to be thin and light, does not support quick battery replacement, and energy input depends entirely on charging and data ports. At present, a fast charging method is generally used to prolong the battery life of the mobile terminal. [0003] Fast charging is realized by increasing the output power of the adapter, wherein, the output power of the adapter=the output voltage of the adapter×the output current of the adapter. Therefore, the output...
