1 Circuit boardPCB description：
1.1 Name:PW4053, USB C port 5V input, three series1A lithium battery charging management board
1.2 Applications: Convenient charging devices, etc.
1.3 Battery pack: 11.1V lithium battery pack, multiple parallel or three series connection , full 12.6V
1.4 Input voltage:5V （ When charging, thelight will be on, and when it is fully charged, the light will turn） , Max chargingcurrent ： 1A
1.5 Introduction to Chip Functions ：
1， Lithium battery charging circuit ：PW4053
PW4053 Lithium battery charge management chip， Up to 1A charging current， support three series lithium battery charging.
2， Circuit diagram ：
PCB layout is divided into two parts: signal controlcircuit + power circuit
Note 1： Theblue thick line is the power trace, the layout should be wide,； SW part (Q1, D1, L1 three devices connected) is not only the poweroutput, but also it is a noise source, the layout should be wide and the area should be small.
Note2： Thered thick line is the power ground, the main points of the drawing board: to be wide, the shorter the distance between the connecting loops at each point, the more holes are punched in the ground.(input, C1, C2, C3,C4,C5, PW4052 bottom pad and battery ground)
