XL4015 DC-DC Step-Down Converter by Kuongshun — adjustable 4–38V input, 1.25–36V output, up to 5A with built-in LED voltmeter display. High-efficiency buck module with thermal shutdown, current limit, and short-circuit protection for power projects.

 

The Kuongshun XL4015 is a high-power adjustable DC-DC step-down (buck) converter module that reduces an input voltage of 4V–38V to a regulated output of 1.25V–36V at up to 5A continuous current. Built around the XL4015 PWM controller IC, this module outperforms the common LM2596 in both current capacity and efficiency, making it the go-to choice for makers, engineers, and hobbyists who need reliable, adjustable power conversion in their projects.

Key Features

  • High Power Output: Delivers up to 4A/50W continuously, and up to 75W with an added heatsink → handles demanding loads that LM2596 modules cannot
  • Built-in LED Voltmeter Display: On-board digital display shows real-time voltage → no need for a separate multimeter during setup
  • Switchable Measurement: Display toggles between input and output voltage with indicator → full visibility of your power circuit at a glance
  • Auto-Calibrating Voltmeter: The voltmeter calibrates automatically → accurate readings without manual adjustment
  • Voltmeter Power-Off Option: Display can be shut down independently → reduces quiescent current draw when monitoring is not needed
  • Thermal Shutdown Protection: Built-in over-temperature cutoff → protects the module and connected components from heat damage
  • Current Limit Function: Integrated current limiting → prevents overcurrent damage to load and module
  • Output Short-Circuit Protection: Built-in short-circuit protection → safe operation even under fault conditions
  • Screw Terminal Connectors: Easy-to-use connection terminals for input and output wiring → fast, tool-free connections for prototyping and permanent installs

Compatibility

  • Arduino UNO / Mega (5V logic): Use this module to step down a higher supply (e.g. 12V battery) to a stable 5V for powering Arduino boards and peripherals.
  • ESP32 / Raspberry Pi (3.3V logic): Set the output to 3.3V to power ESP32 or RPi from a higher-voltage source such as a 12V or 24V supply.
  • General DC Projects: Compatible with any system requiring a regulated DC voltage within the 1.25V–36V output range, provided the input is within 4V–38V.

Typical Applications

  • DIY power supply: Build a bench or portable adjustable power supply for your workshop — a popular project among electronics hobbyists searching for a compact buck converter module.
  • Battery-powered systems: Step down a LiPo or lead-acid battery pack to the exact voltage your microcontroller or sensor array needs.
  • Solar energy projects: Regulate solar panel output to charge batteries or power devices at a stable voltage.
  • LED driver: Power high-power LED strips or arrays from a higher-voltage DC source with precise current and voltage control.
  • Automotive / vehicle electronics: Convert a 12V or 24V vehicle supply to 5V or 3.3V for onboard electronics — within the module's rated input range.

FAQ

Q: Can I power an Arduino UNO directly from the output of this module?
A: Yes. Set the output voltage to 5V and connect it to the Arduino's 5V pin (not Vin), ensuring your input source is higher than 5V and within the 4V–38V input range.

Q: Do I need a heatsink for the XL4015 module?
A: For loads approaching 4A–5A or power dissipation above 50W, adding a heatsink to the IC is strongly recommended to prevent thermal shutdown and ensure stable long-term operation.

⚠ Warning: Do not exceed 38V on the input. Ensure the output voltage is set correctly before connecting sensitive loads. Operating at maximum current without adequate heatsinking may trigger thermal shutdown.
