How to Use XL6015 BUST CONVERTOR : Examples, Pinouts, and Specs

The XL6015 is a high-efficiency, step-up (boost) DC-DC converter module capable of driving a 0.8A load with excellent line and load regulation. This module is widely used for converting lower input voltages to higher output voltages, making it ideal for applications where a stable power supply at a higher voltage level is required. Common applications include battery-powered devices, portable electronics, and power supply for electronic equipment.

• Input Voltage Range: 5V to 32V DC
• Output Voltage Range: 5V to 35V DC (adjustable via onboard potentiometer)
• Output Current: Up to 0.8A (with proper heat sinking)
• Switching Frequency: 400kHz
• Efficiency: Up to 94% (depends on input/output voltage, current, and voltage differential)

1. Connecting Power: Connect the input voltage (5V to 32V DC) to the VIN and GND pins. Ensure that the input voltage does not exceed the specified maximum to avoid damage.
2. Adjusting Output Voltage: Turn the onboard potentiometer to adjust the output voltage. Use a multimeter to monitor the VOUT pin until the desired voltage is reached.
3. Load Connection: Connect the load to the VOUT and GND pins. Ensure that the load does not draw more than 0.8A to maintain module performance.
4. Enabling/Disabling the Module: The EN pin can be used to enable or disable the module. Pulling this pin to ground will disable the module, conserving power when not in use.

• Heat Dissipation: If the module is expected to deliver high output currents or if there is a significant voltage difference between input and output, proper heat sinking or airflow should be provided to prevent overheating.
• Input Capacitor: It is recommended to use a good quality electrolytic capacitor at the input to minimize voltage spikes and provide a stable voltage source.
• Output Capacitor: Similarly, an electrolytic capacitor at the output can help maintain a stable output voltage during transient load changes.
• Inductive Loads: If driving inductive loads, a diode may be necessary across the load to protect the module from voltage spikes.

• Output Voltage Not Adjusting: Ensure the potentiometer is functioning correctly and that the connections to the VOUT pin are secure.
• Module Overheating: Check the current draw of the load and ensure it is within the module's limits. Improve heat dissipation if necessary.
• No Output Voltage: Verify that the input voltage is within the specified range and that the EN pin is not pulled to ground.

• Check Connections: Loose connections can often cause issues. Ensure all connections are secure and well-soldered.
• Measure Input Voltage: Use a multimeter to confirm that the input voltage is within the specified range and is stable.
• Inspect for Damage: Look for any visible signs of damage to the module, such as burnt components or traces, which could indicate a failure.

Q: Can I use the XL6015 to charge batteries? A: Yes, but you must ensure that the output voltage is set correctly for the battery type and that the charging current does not exceed the module's limit.

Q: What is the maximum input voltage for the XL6015? A: The maximum input voltage is 32V DC. Exceeding this voltage can damage the module.

Q: How can I enable or disable the module using an Arduino? A: You can connect the EN pin to an Arduino digital pin and set it HIGH to disable the module or LOW to enable it. Remember to configure the pin as an output in your Arduino sketch.

// Example code to enable/disable XL6015 using an Arduino UNO
const int enablePin = 7; // Connect the EN pin of XL6015 to digital pin 7

void setup() {
  pinMode(enablePin, OUTPUT);
  // To enable the XL6015, set the enablePin LOW
  digitalWrite(enablePin, LOW);
}

void loop() {
  // Your code here
  // To disable the XL6015, set the enablePin HIGH
  // digitalWrite(enablePin, HIGH);
}

Q: Is it possible to get a higher output current than 0.8A? A: The XL6015 is rated for 0.8A without additional cooling. To exceed this, you would need to provide significant heat dissipation, but it is not recommended as it may reduce the lifespan of the module or cause it to fail.
