The LM2596 module is a popular, affordable (approx. 100-250 INR) DC-DC step-down (buck) converter, widely used to efficiently reduce higher DC voltages (4V-40V) to lower, adjustable outputs (1.25V-37V) with a 2A-3A load capacity. It is popular for electronics projects (Arduino/robotics), often featuring onboard adjustments, LED voltmeters, and, with significant loads, typically requiring a heatsink for stability.Key Features & SpecificationsModule Type: Step-down (Buck) Regulator.Input Voltage: 3V to 40V DC (best results with 4V+).Output Voltage: Adjustable from 1.25V to 35V / 37V.Output Current: Typical 2A (up to 3A with heat management).Efficiency: High efficiency (up to 73% under 12V 3A load).
