Instructions:

  1. Input Voltage (VIN):

    • Ensure the input voltage is within the range of 4.5V to 14V.
    • Avoid exceeding the maximum input voltage to prevent damage.
  2. Output Voltage (VOUT):

    • The output voltage is fixed at 5V. No adjustment is required.
  3. Output Current (IOUT):

    • The module can provide a continuous output current of up to 3.3A. Ensure the load does not exceed this limit to avoid overheating or damage.
  4. Efficiency (η):

    • The typical efficiency is 88%. This value may vary depending on the input voltage and load conditions.
  5. Switching Frequency (fSW):

    • The switching frequency is typically 1.5MHz. This helps in reducing the size of external components like inductors and capacitors.
  6. Quiescent Current (IQ):

    • The quiescent current is typically 30μA. This low current consumption makes the module suitable for battery-powered applications.
  7. Load Regulation (ΔVOUT):

    • The load regulation is typically 0.5%. This ensures that the output voltage remains stable even when the load changes.
  8. Line Regulation (ΔVOUT):

    • The line regulation is typically 0.5%. This ensures that the output voltage remains stable even when the input voltage changes.
  9. Output Ripple (VRIPPLE):

    • The output ripple is typically 30mV peak-to-peak. Use appropriate filtering if lower ripple is required.
  10. Operating Temperature (TOP):

    • The module can operate within the temperature range of -40°C to 85°C. Ensure proper heat dissipation in high-temperature environments.
  11. Storage Temperature (TSTG):

    • The module can be stored within the temperature range of -40°C to 125°C.
  12. Mounting:

    • Mount the module on a PCB with appropriate thermal management to ensure reliable operation.
  13. Capacitors and Inductors:

    • Use recommended external components for optimal performance. Refer to the datasheet for specific values and types.
  14. Testing:

    • Before finalizing the design, test the module under various operating conditions to ensure it meets the required specifications.
