The LM2596 DC-DC Step Down Buck Converter Module is a high-efficiency power regulation solution designed for robotics, embedded systems, and electronics projects. Based on the reliable LM2596 switching regulator IC, this module efficiently converts higher DC voltages into stable, lower output voltages with minimal power loss.

Supporting a wide input voltage range from 4V to 40V, the module provides an adjustable output voltage between 1.25V and 37V, easily set using the onboard multi-turn potentiometer. With a maximum output current of up to 3A (with adequate cooling), it is suitable for powering microcontrollers, sensors, communication modules, motors, and IoT devices.

The buck converter operates at a 150 kHz switching frequency, enabling compact design while maintaining high efficiency of up to 92%. Built-in protections such as thermal shutdown and current limiting ensure safe and reliable operation even under demanding conditions.

Commonly used in Arduino, Raspberry Pi, ESP32, battery-powered systems, robotics power distribution, automotive electronics, and industrial automation, the LM2596 module is an essential power management component for both beginners and professionals.
