  • Wide 3.2 V to 35 V input range suits many sources
  • Delivers up to 3 A for small-load power needs
  • LM2596 buck topology steps voltage down efficiently
  • Clear IN+/IN-/OUT+/OUT- labels simplify wiring

Vszerda LM2596s Adjustable Buck Module

The Vszerda LM2596s is a DC-DC step-down converter that accepts 3.2V to 35V input and delivers an adjustable 1.25V to 35V output at up to 3A. It suits hobbyists, students and engineers who need a compact, breadboard-friendly regulator for prototyping, test benches or permanent low-power installations.

Replacing Fixed-Voltage Supplies

Swap fixed-output wall-warts or linear regulators when the project demands a precise voltage not available off the shelf. The module is worth the change whenever the load stays within the 3A limit and the input source exceeds the desired output by at least the dropout margin.

Wiring Into A Prototype Build

Connect IN+ and IN- to the source, then set the output with the onboard potentiometer before wiring OUT+ and OUT- to the load. The four-pin layout keeps the power path clear on a perfboard or stripboard, freeing bench space that a bulky adjustable bench supply would occupy.

Questions about this item

What are the IN+ and IN- terminals used for on this buck converter?

IN+ is the positive input and IN- is the negative input for the 3.2V to 35V supply voltage.

How do I set the output voltage on the LM2596s module?

Adjust the onboard potentiometer while measuring OUT+ and OUT- until the output reads between 1.25V and 35V.

When should I consider replacing this step-down module?

Replace it if the output voltage can no longer be adjusted within the 1.25V to 35V range or the 3A current limit is exceeded repeatedly.
