The LM2596HV Power Supply Module – DC/DC and AC/DC is a highly efficient step-down (buck) voltage regulator designed for powering a wide range of electronic circuits and devices. Supporting both AC (5V–30V) and DC (5V–50V) inputs, this module delivers a stable and adjustable DC output between 3.3V and 33V, making it ideal for battery charging, embedded power systems, solar regulation, and DIY robotics applications. Built around the reliable LM2596HV chip, it ensures up to 92% conversion efficiency, minimizing heat generation and power loss. The module also features multiple protection mechanisms—over-current, over-temperature, and short-circuit—to guarantee safe and stable operation. With easy-to-use screw terminals, passive cooling, and a compact mountable PCB, the LM2596HV is an excellent solution for voltage step-down requirements in both industrial and hobbyist environments.
