About this product
Adjustable step-down module built around an LM2596 switching regulator, specified by Texas Instruments at 150 kHz and 3 A, with the output set by an onboard potentiometer. It efficiently powers 5 V or 12 V electronics, LED strips, and logic boards from a higher DC rail. Continuous current in practice is limited by the inductor, diode, and cooling, so the output should be set with a meter and the module derated.
