MP2155 converts voltage to achieve 2 to 5.5V to 3.3V, suitable for various batteries and supercapacitors

Overview

1. According to the chip data manual, soldering is a bit difficult. The first time I failed to solder by myself, the second time I used Jialichuang's SMT.

2. A 10k resistor can be added to the output end to stabilize the load voltage.

3. According to the data manual of the chip, if the jumper cap is connected to the top, the chip will enter PSM (power save mode) when the current is less than 100ma. If the jumper cap is connected to the bottom, it will not enter this mode.
