## Overview

The JZK XL4015 is a high-performance 5A DC-DC adjustable buck converter module supporting input voltages from 4V to 38V and output voltages from 1.25V to 36V. With a robust operating temperature range (-40°C to 85°C), 96% conversion efficiency, and built-in protections against short circuits and overheating, it’s engineered for reliable, efficient power regulation in diverse applications including automotive, industrial, and DIY electronics. This pack includes two compact modules (51x26x18mm) designed for PCB mounting, delivering up to 75W output power with constant current and voltage capabilities.

## Description

Package contains: 2 pcs 5A DC-DC adjustable step down converter module. Parameters: input voltage: 4V - 38V (Note:input voltage not over 38V), output voltage: 1.25V - 36V DC (continuously adjustable), output current: max. 5A (Recommended to use within 4.5A), output power: within 75W. working temperature range from -40 to 85°C support working frequency of 180KHz, conversion efficiency is 96%. Has power indicators Short circuit protections (limit current 8A) Over-temperature protection which means the output will be automatically turned off after over-temperature. Install required screws: 4 pieces of 3 mm screws (not included) Size: 51 x 26 x 18 mm. Widely Used: This module work for step-down field where the input voltage is higher than the output voltage, like battery, power transformer, DIY adjustable regulated power supplies, 24V car pen style power supplies, industrial equipment step-down, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V and more. This module has constant voltage and constant current function (CC CV). and it has a good performance when you use it as a charger. NOTE: When the module charges a battery, it first use constant current to protect the battery. check the curse above. If you found that the output voltage of the module cannot be adjusted and it's always equal to the input voltage, please turn the potentiometer counterclockwise more than 10 turns and use the module to adjust the voltage normally. The original output voltage is around 20V. If you found that the output voltage of the module cannot be adjusted and it's always equal to the input voltage, please turn the potentiometer counterclockwise more than 10 turns and use the module to adjust the voltage normally.

Review: Operating exactly as required with both voltage and current limiting ability. - Requires a lot of adjustment to get both voltage and current to required outputs, but having done so works brilliantly. Be sure to check with a multimeter before attaching to the device to be powered.
Review: Works fine - With a 12V input and 9V 1A output, running it in constant current mode it gets extremely hot, turns out I had the input ground and output ground on a common rail but the constant current sense shunt is on the outputs negative connection!

### ⭐⭐⭐⭐⭐ Operating exactly as required with both voltage and current limiting ability.
*by S***H on 28 December 2022*

### ⭐⭐⭐⭐⭐ Works fine

With a 12V input and 9V 1A output, running it in constant current mode it gets extremely hot, turns out I had the input ground and output ground on a common rail but the constant current sense shunt is on the outputs negative connection!

### ⭐⭐⭐⭐ Tricky to set up
*by R***P on 17 July 2025*

With some tweaking, this module works just fine. Using a multimeter and a close eye on the leds as you adjust the current flow you can get it in the sweet spot. However, there's no way it will handle 5A without some active heat control.
