Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the operating range of 6.5V to 42V to avoid damage to the device.

2. Output Configuration:

   • The LM3402MM/NOPB provides a fixed output voltage of 3.3V. Verify that this matches your system requirements.

3. Load Current:

   • The device can supply up to 1.5A continuously, with typical operation at 1A. Design your load to stay within these limits.

4. Efficiency Considerations:

   • For optimal efficiency, operate under nominal conditions where the device typically achieves 85% efficiency.

5. Switching Frequency:

   • Operates at a typical switching frequency of 1.5MHz. Ensure this does not interfere with other components in your circuit.

6. Quiescent Current:

   • The quiescent current is very low, around 10μA, which helps in minimizing power consumption during no-load conditions.

7. Dropout Voltage:

   • The dropout voltage is approximately 400mV at maximum load, ensuring stable regulation even when the input voltage is close to the output voltage.

8. Thermal Protection:

   • The thermal shutdown activates at approximately 160°C to protect the device from overheating.

9. Package Information:

   • The device comes in an SOIC-8 package, suitable for surface-mount applications. Ensure proper soldering and handling techniques are used during assembly.

10. Layout Recommendations:

    • Place input and output capacitors as close as possible to the device to minimize noise and improve transient response.
    • Follow recommended PCB layout guidelines to ensure optimal performance and reliability.
