LM2596 DC-DC Step-Down Converter Module
The LM2596 DC-DC Buck Converter Module is a high-efficiency switching voltage regulator designed to convert a higher DC input voltage into a lower adjustable DC output voltage. It uses the LM2596 switching regulator IC and provides a compact, reliable, and efficient power supply solution for electronic projects.
This module accepts an input voltage from 4V to 40V DC and provides an adjustable output voltage from 1.25V to 35V DC using the onboard multi-turn potentiometer. It is widely used in Arduino projects, battery-powered devices, LED applications, and DIY power supplies.
