DC-DC step down converter XL4015 75w / 4-38v to 1.25-35V

The DC-DC Step Down Converter XL4015 75W (4.38 V to 1.25-35 V) is a high-efficiency buck converter module designed to step down a higher DC input voltage (starting around 4.38 V) to a stable, adjustable DC output voltage ranging from 1.25 V to 35 V with up to 75 W power capacity. This makes it suitable for a wide range of electronics projects, microcontroller power supplies, LED drivers, battery systems, and DIY applications requiring a reliable regulated power source.

Featuring the XL4015 switching regulator chip, the module delivers high efficiency and stable output with a simple potentiometer adjustment for fine-tuning the output voltage. Its compact design and robust performance make it suitable for applications with limited space and relatively high current demands.

Module performance and characteristics:
Power indicator light
Voltage meter and voltage meter self calibration. Adopts more advanced voltage microprocessor, voltage meter error + 0.05V, range 0~40V. (Note: to ensure the accuracy of voltmeter, please ensure that the input voltage is above 4.5V)
Touch the button to switch the measured input or output voltage, and indicate which voltage is being measured, and save the settings, even when the power is off.
• the voltmeter can be turned off and touch the left button easily when you don't need it.
With wiring terminals, no soldering iron can also be convenient to use, and to retain welding wire wiring point.
Input voltage 4.0~38V. (the input voltage must be above 1.5V higher than the output voltage)
Adjustable output voltage range 1.25V to 35V, adjustable continuously. (the input voltage must be 1.5V higher than the output voltage)
The output current can reach 5A, and it is recommended to be used in 4.5A.
Output power up to 75W.
High conversion efficiency, up to 96% (efficiency is related to input, output voltage, current, pressure difference)
The load adjustment rate of S (I) = 0.8%, voltage adjustment rate S (U) = 0.8%
Overheating protection and short circuit protection function

Self calibration method for on-board voltmeter:
1. onboard voltage meter display output voltage, press the right button for 2 seconds after the release, voltage meter and output voltage indicator "OUT" blinking, the output voltage adjustment mode; similarly, the voltmeter input voltage display, press the right button for 2 seconds after the release, voltage meter and input voltage "IN" lights blinking, the input voltage adjustment mode;
2. touch the right button, a high voltage unit, touch the left button, a voltage reducing unit; because the voltage of a unit value is less than 0.1V, so you need to press 1-5 to see the continuous change of the voltage meter 0.1V, voltage of concrete continuous button several times depending on the current display value of the voltage is displayed high, the fewer the number of;
3. after the voltage adjustment is completed, press the right button for 2 seconds to release, then you can exit the voltage calibration mode, and all parameters are automatically saved out of power.
Note: this kind of adjustment method, you only need to calibrate once, you can get the accurate voltage value on the whole voltage range, this function is to meet your higher precision requirements and design, please feel free to use.
Application range:
This module can be applied in the field of blood pressure is higher than the output voltage of the input voltage, such as battery, power transformer, DIY adjustable regulated power supply, 24V vehicle notebook power supply, industrial equipment, pressure 12V turn 3.3V, 12V turn 5V, 24V turn 5V, 24V turn 12V, 36V turn 24V.
