LM2596 DC-DC Step-Down Power Supply

LM2596S DC-DC Step-Down Power Supply with SMD LED

The LM2596S DC-DC Buck Converter is a highly efficient, step-down switching regulator designed to deliver stable power for various applications. It supports both fixed output voltages (3.3V, 5V, 12V) and an adjustable output version, providing flexibility for diverse projects. With a rated output current of 2A and a maximum capacity of 3A (with a heatsink), this module is ideal for powering microcontrollers, sensors, and other electronic devices.

Operating at a high switching frequency of 150kHz, the LM2596S minimizes the size of required filter components compared to lower-frequency switching regulators. It features excellent line and load regulation, making it a reliable choice for stable voltage outputs.

This module is equipped with a high-precision potentiometer for easy adjustment of the output voltage, and its efficient switch-mode design outperforms traditional linear regulators, especially at higher input voltages.
