About this item

The LM2596S DC-DC Buck Converter is a versatile step-down power supply module widely used in electronics for efficient voltage regulation. It accepts an input voltage range of 3–40V and provides an adjustable output between 1.5–35V, making it suitable for various applications including Arduino projects, robotics, and solar power systems. This module delivers a rated output current of 2A, with a peak capacity of 3A when equipped with an additional heatsink. It operates at a switching frequency of 150 kHz, allowing for smaller filter components and higher efficiency—up to 92%—compared to traditional linear regulators. The LM2596S features built-in short-circuit protection and current limiting, ensuring safe operation under varying loads. Its industrial-grade operating temperature range of -40°C to +85°C makes it suitable for both indoor and outdoor applications. The module is compact, measuring 45×20×14mm, and includes a high-precision potentiometer for fine-tuning the output voltage. For loads exceeding 2.5A or 10W output power, adding a heatsink is recommended to maintain optimal performance. Available at an affordable price, this module is ideal for DIY enthusiasts and professionals seeking reliable voltage regulation in their projects. Its combination of efficiency, durability, and compact size makes the LM2596S a popular choice in power supply design.
