Description:
The XL4015 5A DC-DC Step-Down Adjustable Power Supply Buck Module operates at a fixed 180 kHz PWM frequency, delivering efficient DC voltage conversion from higher to lower levels. It supports loads up to 5A, ensuring minimal ripple and stable voltage regulation, even under varying input and output conditions.
This module is ideal for applications where the input voltage exceeds the output voltage, such as:
- Battery-powered devices
- Power transformers
- DIY adjustable power supplies
- LCD monitors & portable instruments
- Telecom and networking equipment
- Vehicle accessories
- Industrial machinery
With adjustable output voltage, the XL4015 module is suitable for multiple uses, including charging Lithium-ion (Li-Ion) and Lithium-polymer (LiPo) batteries. It can efficiently step down voltages like 12V to 3.3V or 5V, 24V to 5V or 12V, and 36V to 24V, making it a versatile solution for power conversion.
Features:
- High efficiency up to 96%
- Built-in thermal shutdown function
- Built-in current limit function
- In-built output short protection function
- Input reverse polarity protection: None (If required, use a high-current diode in series with the input)
Applications:
1. Use as a Step-Down Module:
-
Adjust the voltage potentiometer to achieve the desired output voltage.
2. Use as a Battery Charger:
- Determine the battery’s float voltage and charging current (e.g., for a 3.7V/2200mAh lithium battery: float voltage = 4.2V, max current = 2.2A).
- Under no-load conditions, set the output voltage to the float voltage using the voltage potentiometer.
- Measure the short-circuit current using a multimeter and adjust the current potentiometer to set the charging current.
- Default factory setting: 0.1 × charging current (During charging, the current gradually decreases. When it drops below 0.1A, the blue LED turns off, and the green LED indicates a full charge).
-
Important: Perform these steps without connecting the battery initially.
3. Use as an LED Constant Current Driver Module:
- Adjust the voltage potentiometer to the required voltage.
- Measure the short-circuit current with a multimeter and set the current potentiometer for LED current.
- Connect the LED after adjustment.
-
Important: Perform adjustments without connecting the LED initially.
Specifications:
- Input Voltage Range: 4V – 38V DC
- Output Voltage Range: 1.25V – 36V DC adjustable
- Output Current: 0 – 5A
- Output Power: 75W
- Efficiency: Up to 96%

Applications & Use Cases
The XL4015 5A DC-DC Step Down Adjustable Power Supply Buck Module with Heatsink is a versatile buck converter used across a wide range of applications including voltage step-down for electronics, battery-powered projects, LED driver circuits, microcontroller power supply, and solar power regulation.
Common use cases:
- Converting 12V car battery to 5V for USB devices
- Powering a Raspberry Pi from a drone battery
- Regulating solar panel output for charging
This product is ideal for electronics hobbyists, IoT developers, and power supply designers.
Technical Tip: Buck converters are more efficient than linear regulators (LM7805). Choose one rated for at least 1.5x your required current. Ensure input voltage is at least 2V above output.
