Arduino Controlled Buck Converter

Hello everyone, welcome back with an interesting Arduino-controlled buck converter electronic project. The project circuit and Arduino code are also provided in this post, So you can easily build this project without fear. The main feature of this buck converter is the ATMEGA328 microcontroller IC. Normal buck converters work with any PWM-controlled IC, but it is very special and accurate.

Circuit Diagram

The provided circuit of the Arduino-based buck converter can able to deliver a higher current in the output section of the circuit. You can also use this circuit as an MPPT solar charge controller. Actually, the buck converter means, The circuit that will be bucking the input voltage. In other words, the input voltage has to be regulated in the output section is called the buck converter.

The major specialty of a good buck converter is delivering high current in the output section without fail. So this circuit is designed for that purpose. The output voltage and high current you can expect. Rotating the attached preset in the circuit board to control the buck voltage.
