How to Use DC-DC Buck Converter 100W.6A 10-90V > 1.5V-60V [Bill Ludwig]: Examples, Pinouts, and Specs

The DC-DC Buck Converter (Part ID: 100W.6A 10-90V > 1.5V-60V) is a high-efficiency step-down voltage regulator designed to convert a higher input voltage (10-90V) to a lower output voltage (1.5V-60V). With a maximum output power of 100W and a current capacity of up to 6A, this converter is ideal for applications requiring stable and adjustable power delivery.

• Powering low-voltage devices from high-voltage sources
• Battery charging systems
• LED lighting systems
• DIY electronics projects
• Industrial automation and control systems

1. Connect Input Voltage:

   • Connect the positive terminal of your power source to the VIN+ pin.
   • Connect the negative terminal of your power source to the VIN- pin.
   • Ensure the input voltage is within the specified range (10-90V).

2. Connect Output Load:

   • Connect the positive terminal of your load to the VOUT+ pin.
   • Connect the negative terminal of your load to the VOUT- pin.

3. Adjust Output Voltage:

   • If the module includes an adjustable potentiometer (ADJ), rotate it to set the desired output voltage.
   • Use a multimeter to measure the output voltage for accuracy.

4. Power On:

   • Turn on the input power source. The module will step down the input voltage to the configured output voltage.

• Heat Dissipation: At high power levels, the module may generate significant heat. Use a heatsink or active cooling to prevent overheating.
• Input Voltage Range: Ensure the input voltage does not exceed the specified range (10-90V) to avoid damage.
• Output Current Limit: Do not exceed the maximum output current of 6A to prevent overloading.
• Polarity: Double-check the polarity of all connections to avoid short circuits or damage.
• Load Testing: Test the module with a dummy load before connecting sensitive devices.

The DC-DC buck converter can be used to power an Arduino UNO from a higher voltage source. For example, if you have a 24V power supply, you can step it down to 5V to power the Arduino.

1. Connect the 24V power supply to the VIN+ and VIN- pins of the buck converter.
2. Adjust the output voltage to 5V using the potentiometer.
3. Connect the VOUT+ pin to the Arduino's 5V pin and the VOUT- pin to the Arduino's GND pin.

Here is a simple Arduino sketch to blink an LED while powered by the buck converter:

// Blink an LED connected to pin 13
void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output
}

void loop() {
  digitalWrite(13, HIGH); // Turn the LED on
  delay(1000);            // Wait for 1 second
  digitalWrite(13, LOW);  // Turn the LED off
  delay(1000);            // Wait for 1 second
}

1. Can this module be used to charge batteries?

   • Yes, but ensure the output voltage and current are set according to the battery's specifications.

2. What happens if the input voltage exceeds 90V?

   • The module may be damaged. Always ensure the input voltage stays within the specified range.

3. Can I use this module for powering sensitive electronics?

   • Yes, but consider adding additional filtering capacitors to reduce noise.

4. Is the module waterproof?

   • No, the module is not waterproof. Use it in a dry environment or enclose it in a protective case.

By following this documentation, you can effectively use the DC-DC Buck Converter for a wide range of applications while ensuring safety and reliability.
