12V/3A DC-DC Buck Converter Module (LM2596)

A compact DC-DC Buck Converter based on LM2596, designed as a direct 7812 replacement. It offers higher efficiency, a wide input range (14–40V), and up to 3A output current. Features : Direct 7812 Replacement: Pin-compatible with standard 7812 linear regulator (IN, GND, OUT). High Current Output: Supports up to 3A continuous load current, much higher than the 7812 (1A max). Wide Input Voltage Range: Operates from 14V to 40V DC, offering greater flexibility compared to linear regulators. High Efficiency: Up to 90% conversion efficiency, significantly reducing heat generation. Compact Size: Miniature PCB design for easy integration in projects with limited space. Low Heat Dissipation: Minimal power loss thanks to switching regulator technology, eliminating the need for bulky heatsinks. Stable Output: Provides regulated 12V output suitable for powering microcontrollers, sensors, and other digital circuits. Dimensions(LXWXH): 23 X19 X15 mm.
