Charging control circuit, chip and method

The invention relates to a charging control circuit, a chip and a method, which are used for improving a traditional boost charging mode, can be combined with a current popular adapter, can adjust the input voltage of a boost circuit to improve the efficiency, and can also control a boost charging chip to exit a boost mode and enter a direct connection mode. And therefore, the charging current of a plurality of lithium batteries can be greatly improved, and the charging time of a terminal product can be shortened. 本申请涉及一种充电控制电路、芯片及方法，是针对传统的升压充电方式进行改进，可以结合当前流行的适配器，可以调节升压电路的输入电压以提升效率，同时还可以控制升压充电芯片退出升压模式而进入直通模式，以进一步降低充电芯片上的损耗，提高充电功率，基于此，可以大大提高多节锂电池的充电电流，缩短终端产品的充电时间。
