Five green circuit boards with blue potentiometers and inductors

Misskit

Misskit LM2596 DC-DC Buck Converter 5 Pack 3.0-40V to 1.5-35V power adapter

SKU CH-23ER-0VK1R

Pack of five LM2596 step-down modules converting 3.0–40 V input to adjustable 1.25–35 V output at up to 92 % efficiency

  • Changer TypePower Converter
  • Adjustable 1.25 V to 35 V output suits diverse projects
  • 92 % conversion efficiency reduces wasted energy
  • Input range 3.0 V to 40 V fits many power sources
  • Built-in thermal shutdown protects against overheating
  • Five modules per pack simplifies multi-circuit builds

Five-Pack Step-Down Converters

This pack contains five LM2596 buck-converter modules that step a DC input of 3.0 to 40 V down to an adjustable 1.25 to 35 V output. Each board uses Sanyo solid capacitors, a 36-thick PCB, high-Q inductors and an LED output indicator. The integrated potentiometer allows precise voltage setting for DIY power banks, monitors, communication gear and similar electronics projects.

Makers Needing Adjustable 1.5-35 V Rails

These modules suit hobbyists and engineers who require multiple compact step-down regulators with thermal shutdown and current-limit protection. They are not for designs that need a boost or buck-boost topology, inputs above 40 V, outputs outside the 1.25-35 V range, or isolated power conversion. Buyers who want more than five identical units or a pre-cased power supply should look elsewhere.

92% Peak Conversion Efficiency

The LM2596 regulator delivers up to 92 percent efficiency while maintaining a minimum 1.5 V differential between input and output. This single figure determines whether the module can meet your thermal budget and battery-life targets in a given application. Verify your worst-case input voltage and load current against this efficiency level before committing to the design.

Questions about this item

What minimum input voltage must my power source provide so each LM2596 module can regulate down to 1.25 V?

Your source must supply at least 3.0 V, and it must stay at least 1.5 V above whatever output voltage you set on the multi-turn potentiometer.

Will the LED output indicator on each module show power status when I chain them with older 5 V equipment?

Yes, the onboard LED lights whenever the module is delivering voltage, so you can confirm operation on any legacy 5 V rail that meets the 3.0 V minimum input.

How can I verify that a module is delivering the exact voltage my project needs after I adjust the potentiometer?

Measure the output pins with a multimeter while the input is live; the reading should match the 1.25 V to 35 V range you dialled in, confirming the regulator is working as intended.
