The XL6009 + LM2596 Automatic Buck-Boost Converter Module is a versatile DC-DC power module that can step up (Boost) or step down (Buck) an input voltage to obtain an adjustable output voltage. It combines an XL6009 boost converter and an LM2596 buck converter on a single PCB, allowing the output to remain within the adjustable range even when the input voltage is either higher or lower than the required output.

The module features separate input and output screw terminals and adjustable potentiometers for setting the required voltage. It is useful for battery-powered projects, solar applications, robotics, Arduino/ESP projects, vehicle electronics, and laboratory power supplies.
