1， Circuit board PCB description：
1.1 Name ： PW2815 Buck Circuit board
1.2 Applications ： Voltage buck converter board
1.3 VIN input voltage ： 4.5V-80V
1.4 VOUT output voltage ： 5V， 3.3V， 24V， 12V
1.5 Introduction to Chip Functions ：
1， Buck chip：PW2815
PW2815 input voltage is 4.5V~80V, you can set the constant voltage output voltage value by R1,R2, current up to 1.5A, package ESOP8.
2 ， Circuit diagram：
Note 1： The blue thick line is the power trace, C1,C2 input capacitor and C4,C5 output capacitor must not be omitted. At the same time C1,C2 should be placed next to 1pins, as close as possible..
Note 2： The red thick line is the power ground, the main points ofthe drawing board: to be wide, the shorter the distance between the connecting loops .
