1Circuit board  PCB description

1.1  Name PW2330 BuckCircuit board

1.2  Applications Voltage buck converterboard

1.3  VIN input voltage 4.5V-30V

1.4  VOUT output voltage 5V3.3V9V12V

1.5  Introduction to Chip Functions

1, Buck chipPW2330

PW2330 input  voltage is 4.5V~30V, you can set the constant voltage output voltage value by  R1,R2, current up to 3A, package ESOP8.

2 Circuit diagram



Note 1: The  blue thick line is the power trace, C1,C3 input capacitor and C8,C9 output  capacitor must not be omitted. At the same time C1,C3 should be placed next to 8pins, as close as possible..

Note 2: The  red 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.
