一般而言,电源杂讯干扰的传播途径可分为下列二大类:??一、普通模式(Normal Mode):简称通模,指的就是二组输入电源线之间的杂讯。这些杂讯大多是由开关动作或者是静态功率转换器等干扰所造成,当这些干扰与正常讯号重叠在一起时,器材元件是无法分辨的,因为正常讯号也是以通模的状态存在。 ??二、共通模式(Common Mode):简称共模,指的是电源与接地之间的杂讯。这部分杂讯的起因多数是因为接地

TI's BQ2057 charging current is only 200mA. Please give me some advice based on the picture above!
Using a 5V2A adapter, a lithium battery is fully charged to 4.1V, but the charging current is less than 200mA, the charging speed is too slow. See the picture, please improve
