DC buck step-down converter

The JacobsParts XL4015 module reduces a DC input between 5 and 36 volts to an adjustable output from 1.25 to 32 volts. It handles peak loads of 75 watts or 5 amps and sustained loads of 50 watts or 3.5 amps, whichever limit is reached first. Hobbyists and technicians use it for battery charging, LED drivers, automotive electronics and micro-controller power supplies.

Replaces larger bench supplies

This compact board substitutes for a bulky adjustable bench supply when the project only needs up to 50 watts continuous. The jump is worth it when space is tight, efficiency matters or a portable test rig is required. It is not suited for applications that demand more than 3.5 amps sustained or input voltages below 5 volts.

Sustained-load behaviour

Continuous operation stays within 50 watts and 3.5 amps while the XL4015 IC switches at 180 kHz, delivering up to 96 percent conversion efficiency. The input must remain at least 1.5 volts above the set output to maintain regulation. A built-in voltmeter with three indicator lights lets the user monitor voltage and current limits in real time.

Questions about this item

What are the exact dimensions I need to clear for the 68x39x15mm module?

The board measures 68 mm long, 39 mm wide and 15 mm tall, so allow at least that much space inside your enclosure plus room for wiring to the screw terminals and USB port.

Which potentiometer do I turn first to avoid damaging the XL4015 IC?

Set the voltage potentiometer to your target output before connecting a load, then adjust the current potentiometer; reversing the order can push the IC past its limits.

When should I replace the XL4015 5A DC Buck Converter?

Replace the module if it no longer holds the set voltage under load, the LED voltmeter stops switching between input and output readings, or the USB port fails to deliver 5 V.
