Instructions:

  1. Input Connection:

    • Connect the input voltage (VIN) to the positive terminal of the power source.
    • Ensure the input voltage is within the range of 2.7V to 5.5V.
  2. Output Connection:

    • Connect the output voltage (VOUT) to the load or circuit requiring a stable 3.3V supply.
    • The maximum continuous output current is 10A.
  3. Ground Connection:

    • Ensure a common ground connection between the input and output circuits.
  4. Heat Dissipation:

    • Use appropriate heat sinking if operating at high currents to maintain the device temperature within the operating range (-40°C to 85°C).
  5. Efficiency Considerations:

    • The typical efficiency is 90% at 3.3V and 5A. Monitor the efficiency at different load conditions to ensure optimal performance.
  6. Shutdown Mode:

    • To enter shutdown mode, set the enable pin to low. The quiescent current in this mode is typically 5mA.
  7. Storage:

    • Store the device in a dry environment with temperatures ranging from -40°C to 125°C.
  8. Handling:

    • Handle the device with care to avoid damage to the pins and solder joints. Follow standard ESD (Electrostatic Discharge) precautions.
