The LM2596 DC-DC Adjustable Step-Down Buck Converter Module is a compact voltage regulator designed to efficiently reduce a higher DC input voltage to a lower, adjustable DC output voltage. It is widely suitable for electronics projects, battery-powered systems, DIY power supplies and other DC voltage regulation applications.

The module supports an input voltage range of 4V–40V DC and provides an adjustable output from 1.25V–37V DC. Output voltage can be conveniently adjusted using the onboard multi-turn potentiometer. The module supports an output current of up to 3A maximum, although practical continuous current capability depends on input/output voltage, load and cooling conditions.

Built around the LM2596S switching regulator, it offers efficient step-down voltage conversion compared with conventional linear regulators. Clearly marked IN+, IN−, OUT+ and OUT− connection points make wiring straightforward for DIY and electronics applications.

It can be used for battery-powered projects, adjustable DC power supplies, LED projects, microcontroller and development-board power supplies, automotive electronics, DIY circuits and other applications that require a stable lower DC voltage from a higher-voltage source.

Important: This is a step-down (buck) converter only and cannot increase the input voltage. Before connecting sensitive devices, adjust the output to the required voltage and verify it using a multimeter.
