R&D Lm2596 DC-DC Buck Converter 4.5-40V 3A Step Down Voltage Regulator Module Power Supply Electronic Hobby Kit

The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. The buck converter consists of thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects. Input Voltage : DC 4V to 35V (input voltage must be 1.5V higher than the output voltage, no boost). Output Voltage : DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A. Working Temperature: -45 ~ +85 deg C.This board comes with inbuilt current limit funciton and output short circuit protection.
