- GND: Ground (Common for Input and Output)
- Vo: Voltage Output (5V)
3.2 Wiring Diagram
Connect your power source and load according to the following diagram:
Connection Steps:
- Connect the positive terminal of your input power source (0.9V-5V) to the V1 pin.
- Connect the negative terminal of your input power source to the GND pin.
- Connect the positive terminal of your 5V load to the Vo pin.
- Connect the negative terminal of your 5V load to the GND pin.
Important: Ensure all connections are secure and correctly polarized before applying power.
4. Operating Instructions
The module operates by boosting a lower input voltage to a regulated 5V output. The output current capability depends on the input voltage:
- With an input of 0.8V, the module can start and provide approximately 7mA output current.
- For input voltages between 1V and 1.5V, the output current ranges from 40mA to 100mA.
- For input voltages between 1.5V and 2V, the output current ranges from 100mA to 150mA.
- For input voltages between 2V and 3V, the output current ranges from 150mA to 380mA.
- For input voltages greater than 3V, the output current can reach 380mA to 480mA.
The module operates at a working frequency of 150KHz with a typical conversion efficiency of 85%.
5. Maintenance
The EGBO DC-DC Step-Up Power Module is designed for reliable operation and requires minimal maintenance. To ensure longevity and optimal performance:
- Keep the module clean and free from dust and debris.
- Avoid exposing the module to excessive moisture or extreme temperatures outside its specified operating range (-40°C to 80°C).
- Do not apply mechanical stress to the module or its components.
- Regularly inspect connections for any signs of corrosion or loosening.
6. Troubleshooting
To prevent damage and ensure proper function, adhere to the following conditions. Failure to do so may lead to module malfunction or damage:
- Module Burnout: The input voltage cannot be greater than the nominal output voltage (5V). Applying an input voltage higher than 5V will likely cause the module to burn out.
- Low Output Voltage: The input power must be greater than the output power. If the input power is insufficient for the desired output load, the output voltage will be less than the nominal 5V. Ensure your power source can supply enough current at the input voltage.
- Output Instability/Low Voltage: The output load cannot exceed the module's nominal load capacity (maximum 480mA). If the connected load draws more current than the module can supply, the output voltage will drop below 5V or become unstable. Reduce the load or ensure the load current is within the module's specifications for the given input voltage.
7. User Tips
- Always double-check your wiring before applying power to prevent short circuits or incorrect polarity.
- Consider adding a small capacitor (e.g., 100uF) across the output terminals if your load is sensitive to voltage fluctuations or draws pulsed current.
- For long-term projects, ensure adequate ventilation around the module, especially if operating near its maximum current capacity, to prevent overheating.
- This module is very small, making it suitable for space-constrained applications. Handle with care during installation.
