LM2596 Buck Converter Module – DC-DC Step Down Power Supply

The LM2596 Buck Converter (Standard Quality) is a compact and efficient DC-DC step-down voltage regulator module, designed to convert higher voltages to a lower, stable output. Based on the LM2596S switching regulator IC, this module supports input voltages from 4V to 40V and provides an adjustable output between 1.25V to 35V, with a maximum current output of 2A (up to 3A with proper heat dissipation).

This versatile power supply module is ideal for powering microcontrollers like Arduino, ESP8266, Raspberry Pi, sensors, and other 5V or 3.3V devices. With a built-in potentiometer, voltage adjustment is simple and precise. It’s perfect for DIY electronics, prototyping, robotics, and embedded systems.
