- Compact 51x26.3x14mm module fits tight spaces
- Stable constant-current regulation via LM358 op-amp
Two-Module Pack for Prototyping
This pack contains two XL4015-based step-down modules that convert a DC input of 8-36V to an adjustable 1.25-32V output. Each board handles up to 5A peak or 3.5A sustained, making them suited for hobbyists powering micro-controllers, LED strings, battery chargers or automotive accessories from a higher-voltage source.
95 % Peak Efficiency, Low Heat
The XL4015 IC and onboard LM358 op-amp deliver up to 95 % conversion efficiency, so a 24V-to-12V 1A test drew only 92.7 % losses as heat. At the sustained 50W limit the compact 51x26.3x14mm board stays cool without forced airflow, and the 180kHz switching frequency keeps ripple low for sensitive analog or digital loads.
Sustained 3.5A Without Thermal Throttle
Under continuous load the module maintains its rated 3.5A output as long as input voltage remains at least 1V above the set output and exceeds 5.6V for current-limit operation. Peak currents to 5A are allowed for short bursts, but prolonged operation at the 75W peak rating will raise temperature; designers should plan for the 50W continuous ceiling in enclosed projects.

Questions about this item
How do I wire the XL4015 buck module and what is the common mistake with input voltage?
Connect DC input to IN+ and IN- (8-36V) and load to OUT+ and OUT-. The input must be at least 1V higher than the set output; reversing polarity or using less than 5.6V input disables current limiting and can damage the board.
What maintenance or replacement will the XL4015 converter need over time?
No scheduled maintenance is required. If sustained loads exceed 50W or 3.5A, or if the module overheats, the XL4015 IC can fail and the whole board must be replaced.
What limit appears first when running the XL4015 continuously at high load?
The sustained rating of 50W or 3.5A (whichever is reached first) is the limiting factor; above that the converter overheats and cannot maintain regulation.
