LM2596 buck converter

The LM2596 DC-DC Buck Converter is a monolithic integrated circuit designed for easy and convenient construction of step-down switching regulators. Operating at a switching frequency of 150 kHz, it allows for smaller filter components compared to lower frequency regulators. This module is ideal for converting input voltages ranging from 3V to 40V down to an adjustable output voltage between 1.25V and 35V, with a maximum output current of 3A (rated 2A). It features high efficiency, low ripple, and includes built-in thermal shutdown and current limiting protection. Common applications include powering microcontrollers (Arduino, ESP32), LED strips, motors, and other DIY electronics projects requiring stable voltage regulation. Choose this module for its reliability, ease of use with a simple potentiometer for voltage adjustment, and robust performance in various power supply scenarios.
