  • Up to 3 A current with low ripple for stable delivery
  • LM2596S buck topology gives efficient step-down conversion
  • Three modules in one pack ready for multiple builds

DC-DC Buck Converter Module Set

This pack contains three step-down power modules that accept up to 60 V input and deliver selectable outputs of 3.3 V, 5 V, 12 V or 24 V. Each board uses an LM2596S regulator rated for 3 A continuous current with low ripple. The adjustable variant can be tuned from 2 V to 34 V by turning the onboard potentiometer clockwise.

Suits fixed-voltage rails and adjustable prototyping

Hobbyists and engineers who need ready-made 3.3 V, 5 V, 12 V or 24 V rails from a higher-voltage source will find the fixed-output versions convenient. The potentiometer-equipped board covers custom voltages between 2 V and 34 V for experimental work. Buyers who require more than 3 A per channel, isolated outputs, or a boost topology should look at other solutions.

3 A maximum output current

The LM2596S controller limits each module to 3 A, so the choice hinges on whether your load stays within that envelope. Exceeding it will trigger thermal protection or damage the converter. Verify your peak draw before committing to this board.

Questions about this item

How often will the LM2596S regulator need replacement under continuous operation?

The LM2596S buck converter is a solid-state component with no moving parts, so it does not require scheduled replacement if operated within its 60 V input and 3 A current limits.

What thermal limit appears first when the module runs at 3 A output for extended periods?

Sustained 3 A loads raise the regulator temperature until its internal thermal shutdown engages, which is the first hard limit reached before any other parameter degrades.

How much audible noise and heat does the converter produce when powering a 24 V load all day?

The synchronous buck design keeps ripple low, so the module runs silently; heat rises proportionally to the voltage drop from the 60 V input to the 24 V output at the drawn current.
