Digital buck converter for 5–36 V inputs
The JacobsParts DCMOD-G XL4015 steps a 5–36 V DC source down to an adjustable 1.25–32 V output with a peak capability of 75 W or 5 A. Onboard push-buttons let you set the voltage in 0.1 V increments while an integrated LED voltmeter toggles between input and output readings. The XL4015 IC runs at 180 kHz and achieves up to 96 % conversion efficiency in a 66 x 39 x 18 mm footprint.
Makers needing precise low-voltage rails
Hobbyists powering 5 V USB gear or LED strips from a 12 V battery will appreciate the fine adjustment and constant-voltage regulation. The module is not suited for driving raw LEDs without external current limiting, and the input must stay at least 1.5 V above the desired output. Builds requiring sustained current above 3.5 A or power above 50 W should consider a different topology.
Sustained loads limited to 50 W
Continuous operation at the peak 75 W / 5 A rating is not supported; the sustained ceiling is 50 W or 3.5 A, whichever is lower. The board ships without a heatsink, so moderate to high continuous loads will need external cooling to keep the XL4015 IC within safe temperatures. Reverse-polarity protection is absent on both input and output terminals.

Questions about this item
What input voltage must I already have available so the XL4015 can produce my target output?
The converter accepts 5V to 36V DC at its input terminals, and the input must be at least 1.5V higher than the output you set.
Will the module run reliably alongside the 12V battery and LED strips I plan to keep in my project?
Yes, it steps a 12V battery down to the 1.25V–32V range your LED strips need, delivering up to 50W sustained or 75W peak while maintaining constant voltage regulation.
How can I confirm the converter is regulating at the voltage I selected after I wire it up?
Press the onboard buttons to set the output in 0.1V steps, then use the built-in voltmeter — switchable between input and output — to verify the exact voltage appearing at the load terminals.
