XL6009 DC-DC Adjustable Step-Up Boost Converter Module

The XL6009 DC-DC Boost Converter Module is a compact, adjustable step-up voltage regulator designed to convert a lower DC input voltage into a higher DC output voltage.

Built around the XL6009E1 switching regulator, this module provides efficient DC voltage conversion for electronics projects, robotics, battery-powered systems, LED lighting, portable equipment and custom power supplies.

Its onboard multi-turn potentiometer allows users to adjust the output voltage to suit their circuit requirements. The module also features an inductor, input/output filtering capacitors and clearly marked solder pads for easy connection.

Unlike a step-down converter, the XL6009 is specifically configured to increase voltage, making it useful when the available DC supply voltage is lower than the voltage required by an electronic device.

Key Features

• XL6009E1 Regulator: High-frequency switching regulator for efficient DC power conversion.
• Step-Up Voltage Conversion: Increases a lower DC input voltage to a higher output voltage.
• Adjustable Output: Approximately 5V to 35V, subject to the input voltage and operating conditions.
• Wide Input Range: 5V to 32V DC operating range.
• High Switching Frequency: 400kHz nominal switching frequency.
• Efficient Operation: XL6009 regulator efficiency can reach up to 94% under suitable operating conditions.
• Multi-Turn Potentiometer: Allows fine adjustment of the output voltage.
• Compact PCB: Includes mounting holes for integration into custom electronic equipment.

Technical Specifications

Important: The XL6009’s 4A internal switching-current rating is not a guaranteed 4A output rating. Actual usable output current depends on the input voltage, selected output voltage, available input power and module temperature.

Applications

1. DIY Adjustable Power Supplies

Build compact adjustable DC power supplies for electronic experiments, testing equipment and laboratory projects.

For example, a suitable 5V DC input can be boosted to 9V or 12V for a compatible low-power electronic circuit.

2. Arduino and Robotics Projects

Provide a higher supply voltage for compatible motors, actuators, sensors and other electronic peripherals in Arduino and robotics systems.

3. Battery-Powered Electronics

Increase the voltage from suitable battery packs to operate electronic devices requiring a higher voltage.

For rechargeable projects using lithium-ion batteries, DIYGH stocks the 18650 Li-ion Rechargeable Battery 3.7V 2500mAh and a 2-Slot 18650 Battery Holder.

Ensure the battery pack provides at least the required input voltage and includes appropriate battery protection.

4. LED Lighting Systems

Boost a lower DC supply voltage to operate suitable constant-voltage LED strips and lighting equipment.

5. Solar and Renewable Energy Projects

Useful for voltage regulation experiments involving suitable low-voltage solar power systems, regulated solar supplies and battery-backed electronics.

6. Electronic Equipment Repairs

Useful for developing replacement power supply circuits and testing equipment requiring a higher regulated DC voltage.

Input and Output Connections

The XL6009 module has four connection pads.

Connect the DC power source to IN+ and IN-, then connect the electronic load to OUT+ and OUT- after setting the required output voltage.

For example, DIYGH’s 12V 2A AC-DC Power Adapter can serve as an input supply for suitable higher-voltage, low-power applications.

How to Adjust the Output Voltage

1. Connect a suitable DC power supply to the input terminals, observing the correct polarity.
2. Keep the intended electronic load disconnected during adjustment.
3. Connect a multimeter across OUT+ and OUT-.
4. Turn the onboard blue potentiometer gradually while observing the output voltage.
5. Adjust the output until the required voltage is reached.
6. Confirm the output voltage and polarity before connecting the load.
7. Monitor the output voltage and module temperature during initial operation.

A suitable instrument such as the ANENG XL830L Digital Multimeter can be used to measure and verify the output voltage.

Boost Converter vs Buck Converter

The XL6009 module is designed to increase DC voltage.

For example:

• 5V input to 9V output
• 6V input to 12V output
• 12V input to 24V output

These examples require an adequate input power source and a load within the module’s operating capability.

If your application requires reducing voltage, such as converting 12V DC to 5V DC, use a step-down regulator instead.

DIYGH also stocks the LM2596 DC-DC Adjustable Buck Converter Module for applications requiring a lower DC output voltage.

Important Usage Information

• Ensure the output voltage is higher than the input voltage.
• Do not connect the module directly to AC mains power.
• Confirm input and output polarity before applying power.
• Always adjust and measure the output voltage before connecting sensitive electronics.
• The module is a constant-voltage converter, not a dedicated lithium battery charging controller.
• The module does not provide a dedicated constant-current output adjustment for high-power LED driving.
• Use suitable ventilation and avoid excessive loading that causes overheating.
• Actual output current capability decreases as the voltage boost ratio increases.
