Arduino Controlled Buck Converter

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

Arduino Buck Converter Circuit Diagram

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

The major speciality 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. By rotating the attached preset in the circuit board to control the buck voltage.
