How to Use XL 6009 Boost Module: Examples, Pinouts, and Specs

The XL6009 Boost Module is a high-efficiency DC-DC adjustable step-up (boost) converter designed to increase a lower input voltage to a higher output voltage. It is based on the XL6009 regulator chip and is capable of driving a load with higher voltage requirements. This module is commonly used in applications such as powering LED strips, motors, and other electronic devices that require a voltage higher than the available source.

• Powering 12V or higher LED strips from a lower voltage source
• Boosting battery voltage to run 5V, 9V, or 12V devices
• Providing adjustable output for prototyping and experimentation
• Solar-powered systems where the input voltage varies

• Input Voltage Range: 3V to 32V
• Output Voltage Range: 5V to 35V (adjustable via onboard potentiometer)
• Maximum Output Current: 4A (peak), recommended 2.5A for continuous use
• Switching Frequency: 400kHz
• Efficiency: Up to 94% (depends on the difference between input and output voltage)

1. Connect the input voltage to the IN+ and IN- pins, ensuring that the voltage is within the specified range.
2. Connect the load to the OUT+ and OUT- pins.
3. Adjust the onboard potentiometer to set the desired output voltage. Turn it clockwise to increase and counterclockwise to decrease the voltage.
4. Verify the output voltage with a multimeter before connecting sensitive electronics.
5. Once the desired voltage is set, the module is ready to power the connected device.

• Always check the polarity of the connections to avoid damage to the module or the connected devices.
• Do not exceed the maximum input voltage and current ratings to prevent overheating and potential failure.
• Use a heat sink if the module is expected to handle currents near the upper limit for an extended period.
• Ensure that the module is properly ventilated to dissipate heat.
• Avoid adjusting the potentiometer while the module is under load to prevent voltage spikes.

• Output voltage is not stable or does not match the setting: Ensure that the input voltage is stable and within the specified range. Check the potentiometer and connections for any issues.
• Module overheats during operation: Verify that the current draw is within the specified limits and that the module is adequately ventilated.

• If the output voltage is incorrect, re-adjust the potentiometer with a small screwdriver while monitoring the voltage with a multimeter.
• If the module overheats, reduce the load or improve cooling with a heat sink or fan.
• In case of erratic behavior, check for any loose connections or potential short circuits in the wiring.

Q: Can I use the XL6009 Boost Module to charge batteries? A: The XL6009 is not designed as a battery charger. It lacks the necessary control features for safe charging.

Q: What is the maximum input current for the XL6009 Boost Module? A: The maximum input current is not explicitly specified, but it should be less than the maximum output current due to efficiency losses. Always ensure the input current is within a safe range for your power source.

Q: How do I know if the XL6009 Boost Module is working correctly? A: Measure the output voltage with a multimeter. If it's within the range you set and remains stable under load, the module is functioning correctly.

// This example demonstrates how to use the XL6009 Boost Module with an Arduino UNO
// to power an external device that requires a higher voltage.

void setup() {
  // No setup required for the boost module itself as it is not controlled by the Arduino.
  // Just ensure that the module's output voltage is correctly set for your device.
}

void loop() {
  // Your code here to interact with the device powered by the XL6009.
  // The boost module will continuously provide the set voltage as long as it is powered.
}

Note: The XL6009 Boost Module is not directly interfaced with the Arduino in terms of control signals; it simply provides a higher voltage output from a lower voltage input. The Arduino code is only necessary if you are controlling or monitoring devices powered by the XL6009.
