Abstract

The invention provides a power adapter, electronic equipment, a charging system and a charging method. The power adapter comprises a first charging interface used for receiving an analog charging signal and a switching instruction of the electronic equipment, a charging circuit used for realizing voltage conversion according to the analog charging signal so as to output a charging voltage suitable for charging the electronic equipment to the electronic equipment through the first charging interface, a first switching circuit used for selectively conducting a first data path and a first charging feedback path, and a first controller used for receiving a switching instruction based on the first data path and enabling the first switching circuit to conduct the first charging feedback path according to the switching instruction. The power adapter can feed back and adjust the output voltage of the charging circuit based on an analog charging signal fed back by the electronic equipment so as to realize closed-loop negative feedback control of the whole charging process. Feedback is rapid, the charging speed is high, and the charging speed can be optimal in the short time.

Description

technical field [0001] The present application relates to the technical field of charging, in particular to a power adapter, electronic equipment, a charging system and a charging method. Background technique [0002] With the rapid development of electronic consumer products, terminal products such as mobile phones, cameras, and tablet computers are increasingly favored by consumers. In order to improve the portability and convenience of use of terminal products, batteries have become an indispensable part of handheld terminal products. Usually, electronic devices are charged through power adapters. However, in the traditional charging method, the charging speed is slow. Contents of the invention [0003] The embodiments of the present application provide a power adapter, an electronic device, a charging system and a charging method, and the charging speed is fast. [0004] A power adapter, comprising: [0005] The first charging interface is used to connect with the e...
