From the project
DC–DC buck (step-down) converter designed in KiCad, including schematic and PCB layout files. The project focuses on efficient voltage regulation and practical PCB design.
This repository contains the complete schematic and PCB design of a DC–DC buck (step-down) converter, created using KiCad. The project demonstrates practical power electronics design, component selection, and PCB layout techniques.
A buck converter is a DC–DC switching regulator used to efficiently step down a higher input voltage to a lower output voltage. This design is suitable for learning, prototyping, and low-to-medium power applications.
