LM2596 LM2577 DC-DC Buck Boost Module 1A

The LM2596 LM2577 DC-DC Buck Boost Module is an adjustable power supply that can step voltage down or up from a single small board. It pairs an LM2596S step-down regulator with an LM2577S step-up regulator, so your output stays at the voltage you set whether the input is higher or lower.

Accepting 3.5V to 28V in, it delivers any output from 1.25V to 26V at a rated 1A, adjusted with an onboard potentiometer. That makes it ideal for battery projects where the cell voltage rises and falls, for running 5V or 12V devices from mixed sources, and for powering sensors, microcontrollers, LEDs, and small motors on the bench. An LED indicator shows power, and mounting holes make it easy to fix in place.

Always set the output voltage with a multimeter before connecting your device, since the output starts wherever the potentiometer was left. It is a flexible, budget-friendly choice for hobbyists, makers, and students who need one module that works for both step-down and step-up jobs.
