Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a charging circuit and electronic equipment. Background technique [0002] Some batteries have limited capacity (such as wireless earphones), which requires that the charging current should not be too large. [0003] The commonly used solution is to control the charging current through a linear charging chip, but the conversion efficiency of this method is low. In order to solve this problem, there are methods on the market that use communication methods to improve conversion efficiency, but frequent communication will increase the charging time. The following are several existing charging methods: [0004] The first charging method uses a linear charging chip for charging. The conversion efficiency of the charged side (such as earphones) is as follows: [0005] [0006] In the formula: Vbat is the voltage of the battery on the charged side; V in is the access voltag...
