From the project

Adjustable DC-DC buck converter using LM2596S-ADJ, converting 5V–40V DC to a regulated output up to 3A.

This project demonstrates the design and implementation of an adjustable DC-DC buck converter using the LM2596S-ADJ IC. The converter accepts a wide input range of 4.5–40V DC and delivers a regulated, adjustable output capable of supplying up to 3A continuous current.

- Complete schematic design in KiCad - LTspice simulation for stability and performance verification - Optimized PCB layout for high efficiency and low output ripple - Power stage, feedback network, and input/output filtering included - Reliable voltage regulation using feedback compensation techniques
