How to Use DC-DC Step-up Boost Converter - 2A - 5V Output: Examples, Pinouts, and Specs

The DC-DC Step-up Boost Converter - 2A - 5V Output by TinyTronics is a compact and efficient power management module designed to increase a lower input voltage to a stable 5V output. This boost converter is capable of delivering up to 2A of current, making it ideal for powering USB devices, microcontrollers, and other 5V electronics from lower voltage sources such as batteries.

• Powering 5V devices from 3.7V lithium-ion batteries.
• Boosting voltage in portable electronics and battery-powered systems.
• Supplying power to USB-powered devices.
• Applications in robotics, IoT devices, and embedded systems.

Below are the key technical details for the DC-DC Step-up Boost Converter - 2A - 5V Output:

The module has four pins for input and output connections:

1. Connect the Input Voltage:

   • Connect the positive terminal of your power source (e.g., battery) to the VIN+ pin.
   • Connect the negative terminal of your power source to the VIN- pin.
   • Ensure the input voltage is within the range of 2V to 24V.

2. Connect the Output Load:

   • Connect the positive terminal of your load (e.g., a 5V device) to the VOUT+ pin.
   • Connect the negative terminal of your load to the VOUT- pin.

3. Power On:

   • Once connected, the module will automatically boost the input voltage to a stable 5V output.

4. Verify Output:

   • Use a multimeter to confirm the output voltage is 5V before connecting sensitive devices.

• Input Voltage Range: Ensure the input voltage does not exceed 24V or drop below 2V to avoid damaging the module.
• Current Limitations: The module can deliver up to 2A at 5V. Exceeding this limit may cause overheating or failure.
• Heat Dissipation: For high-current applications, ensure proper ventilation or add a heatsink to prevent overheating.
• Polarity Protection: Double-check the polarity of your connections to avoid damaging the module.

The boost converter can be used to power an Arduino UNO from a 3.7V lithium-ion battery. Below is an example circuit and code:

1. Connect the battery's positive terminal to VIN+ and negative terminal to VIN-.
2. Connect VOUT+ to the Arduino UNO's 5V pin.
3. Connect VOUT- to the Arduino UNO's GND pin.

// Example code to blink an LED on Arduino UNO powered by the boost converter
// Ensure the boost converter is providing a stable 5V to the Arduino UNO.

void setup() {
  pinMode(13, OUTPUT); // Set pin 13 as an output for the onboard LED
}

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. No Output Voltage:

   • Cause: Incorrect input connections or insufficient input voltage.
   • Solution: Verify the input voltage is within the 2V to 24V range and check the polarity of the connections.

2. Overheating:

   • Cause: Excessive current draw or poor ventilation.
   • Solution: Ensure the load does not exceed 2A and provide adequate cooling.

3. Output Voltage Not Stable:

   • Cause: Input voltage too low or fluctuating.
   • Solution: Use a stable power source and ensure the input voltage is at least 2V.

4. Device Not Powering On:

   • Cause: Faulty connections or damaged module.
   • Solution: Check all connections and replace the module if necessary.

Q: Can I adjust the output voltage?
A: No, the output voltage is fixed at 5V and cannot be adjusted.

Q: Can I use this module with a solar panel?
A: Yes, as long as the solar panel's output voltage is within the 2V to 24V range.

Q: Is the module protected against reverse polarity?
A: No, the module does not have built-in reverse polarity protection. Always double-check your connections.

Q: What is the efficiency of the module?
A: The efficiency can reach up to 92%, depending on the input voltage and load conditions.
