High-efficiency adjustable DC-DC buck module. Supports a wide input range from 5V to 80V, delivering up to 0.8A output current with built-in thermal and short-circuit protection.

Bridge the gap between high-voltage batteries and low-voltage electronics. The XL7015 Buck Module is a versatile power solution for projects requiring a significant voltage drop. Whether you are tapping into a 48V e-bike battery or a 24V industrial rail, this module provides the precision control needed to safely power 5V or 12V microcontrollers and sensors.

Probots™ ProSpec Grade High-Voltage Integrity Unlike generic buck converters limited to 35V or 40V, the XL7015 is Probots™ ProSpec Grade , featuring a maximum input tolerance of 80V. It utilizes a high-frequency switching architecture (150KHz) to maintain high efficiency even when stepping down from extreme voltages. The board is designed with large VIN and VOUT solder pads and a precision W103 multi-turn potentiometer, allowing you to lock in your desired output voltage with 0.1V accuracy.

Note: In a new module, make sure you set the output voltage before connecting the load. Modules will be set to output high voltage by default.

Instruction :

  • Use as a step-down module to convert high input voltage to low output voltage
  • Adjust the “voltage potentiometer” so that the output voltage reaches the value you want
  • Use as a LED constant current driver module
  • Adjust the “voltage potentiometer” so that the output voltage reaches the value you want
  • Use a multimeter to measure the output short-circuit current, while regulating the “current potentiometer” so that the output current reaches a predetermined LED operating current
    Connect LED, work

Specifications

  • Input Voltage Range: 5V to 80V DC

  • Output Voltage Range: 5V to 20V DC (Continuously Adjustable)

  • Output Current: Maximum 0.8A

  • Conversion Efficiency: Up to 85%

  • Switching Frequency: 150KHz

  • Output Ripple: < 50mV

  • Protections: Over-temperature, Short-circuit, Current limiting

  • Board Dimensions: ~44mm x 16mm

Key Applications & Projects

  • Electric Vehicles (EV/E-Bike): Dropping high-voltage battery packs (36V/48V/60V/72V) to 5V or 12V for lights, GPS, or USB chargers.

  • Industrial Automation: Converting 24V PLC power rails to 3.3V/5V for custom sensors.

  • Power over Ethernet (PoE): Extracting usable DC power from high-voltage networking lines.

  • Solar Power Systems: Managing fluctuating high-voltage solar panel outputs for battery charging or IoT nodes.

Unlock New Capabilities (Project Evolution)

  • Feature Upgrade: The XL7015 replaces bulky heat-generating linear regulators like the LM7805 in high-voltage setups. It converts excess voltage into current rather than heat, significantly extending your battery life.

  • Effort Level: Beginner. Requires basic soldering to attach input and output wires.

Virtual Technician & Tips

  • Probots™ Logic-Safe Setup: Always connect your multimeter to the VOUT/GND pads and adjust the potentiometer before connecting your sensitive electronics. This ensures your project never sees an accidental over-voltage spike.

  • Pro Tip: For input voltages above 60V, we recommend adding a small electrolytic capacitor across the VIN and GND pads to absorb any initial voltage ripples or in-rush current.

PACKAGE INCLUDED

  • 1 x XL7015 DC-DC Step-Down Adjustable Buck Module

FREQUENTLY ASKED QUESTIONS (FAQ)

  • What is the maximum input voltage? This module safely handles up to 80V DC.
  • Can it step up voltage? No, this is a "buck" or step-down converter; the output voltage must always be lower than the input.
  • What is the maximum output current? It is rated for a continuous maximum of 0.8A.
  • Is it reverse polarity protected? No, connecting the input voltage backward (VIN to GND) will damage the module instantly.
  • How do I adjust the output voltage? Turn the brass screw on the blue "W103" potentiometer using a small screwdriver while monitoring the output with a multimeter.
  • Does it get hot during operation? Due to its switching design, it stays much cooler than a linear regulator, but it may get warm if drawing the full 0.8A at high voltage drops.
  • What is the minimum input voltage needed for 12V output? The input must be at least 1-2V higher than the desired output (approx. 14V for a stable 12V output).
  • Can I use this for 24V industrial systems? Yes, it is excellent for 24V to 5V conversions.
  • Is it compatible with 72V e-bike batteries? Yes, it handles up to 80V, making it perfect for 72V systems that might peak at 78V-79V when fully charged.
  • What are the mounting hole sizes? This module is designed for direct soldering or breadboard mounting and does not include dedicated screw mounting holes.
  • Can I use it to charge a phone? Yes, if adjusted to 5.0V, it can provide up to 0.8A for charging mobile devices.
  • What is the switching frequency? It operates at approximately 150KHz.
  • Is the output voltage stable? Yes, it features an internal feedback loop to maintain a consistent output voltage even as the input voltage fluctuates.
  • What does "W103" mean on the part? It identifies the 10k Ohm multi-turn potentiometer used for voltage adjustment.
  • Does it include the wires? No, you must solder your own wires to the designated pads.
  • Is there a power LED indicator? This specific board layout does not feature a power LED to save on quiescent current draw.
  • Can I parallel two of these for more current? Paralleling buck converters is not recommended without specialized load-sharing circuitry.
  • What is the board size? It is approximately 44mm long and 16mm wide.
  • Can it handle 80V AC? No, this is a DC-DC converter only.
  • Is it CE/RoHS compliant? The PCB features standard compliance markings on the bottom layer.
