Microcontroller power module solution based on IP5306

· I have always hoped to have an easy-to-use microcontroller power supply solution. I referred to many examples online and combined with the cost, I finally selected the ip5306 chip.

The advantages are as follows:

1. Support 2.4A synchronous boost.

2. Supports 2.1A battery charging current.

3. Supports flushing and placing at the same time.

4. Low ripple output.

5. The peripheral components are simple and easy to transplant.

6. Low price (1.1 yuan)

Not much BB, just go to the picture:

Front view (the author did not solder to test the 3.3v voltage output of the 1117 chip due to time constraints, you can solder by yourself)

Rear view

The following is the output ripple test:

The output is almost ripple-free and very clean (compared to the previous solution using sy3511, it is not at the same level...)

You can buy the original parts on Taobao, and the whole set costs about 3 yuan (ip53061.1 yuan for inductor 0.7 yuan, kma1117 0.4 yuan, other chip capacitors and resistors 0.8 yuan)
