2, Buck chipPW2052

PW2052 input  voltage is 2.5V ~5.5V, you can set the constant voltage output voltage value by  R1,R2, current up to 2A, package SOT23-5.

3, Buck chipPW2052B

PW2052B input  voltage is 2.3V ~6V, you can set the constant voltage output voltage value by  R1,R2, current up to 2A, package SOT23-6.

4, Buck chipPW2053

PW2053 input  voltage is 2.5V ~5V, you can set the constant voltage output voltage value by  R1,R2, current up to 3A, package SOT23-5.

5, Buck chipPW2058

PW2058 input  voltage is 2V ~6V, you can set the constant voltage output voltage value by  R1,R2, current up to 0.8A, package SOT23-5.

2, Circuit diagram



Note 1: The  blue thick line is the power trace, C1 input capacitor and C3 output capacitor must  not be omitted. At the same time C1,C2 should be placed next to 4 pins, as  close as possible.

Note 2: The  red thick line is the power ground, the main points of the drawing board: to  bewide, the shorter the distance between the connecting loops at each point.
