Instructions for Use

1. Input Connection:

   • Connect the input voltage (VIN) to the designated input pin.
   • Ensure the input voltage is within the specified range (4.5V to 28V).

2. Output Configuration:

   • Set the output voltage (VOUT) using external resistors according to the datasheet formula.
   • The typical output voltage is 5V, but it can be adjusted.

3. Output Load:

   • The device can provide a continuous output current of up to 3.5A.
   • For optimal performance, keep the load within the recommended range.

4. Efficiency:

   • The efficiency is typically 95% at 5V and 3A.
   • Monitor the efficiency under different load conditions to ensure optimal performance.

5. Switching Frequency:

   • The switching frequency is set to 600kHz.
   • This frequency helps in reducing the size of external components.

6. Quiescent Current:

   • The quiescent current is typically 100μA when there is no load.
   • This low quiescent current helps in reducing power consumption.

7. Regulation:

   • The load regulation is ±1%, ensuring stable output voltage under varying loads.
   • The line regulation is ±0.5%, maintaining output stability over the input voltage range.

8. Ripple and Noise:

   • The ripple and noise on the output are typically 30mV peak-to-peak.
   • Use appropriate filtering techniques to further reduce ripple and noise if necessary.

9. Temperature Considerations:

   • The operating temperature range is -40°C to 125°C.
   • The storage temperature range is -65°C to 150°C.
   • Ensure proper heat dissipation to avoid overheating.

10. Protection Features:

    • The device includes overcurrent, overvoltage, and thermal protection.
    • These features help in protecting the device from damage under fault conditions.

11. Layout Recommendations:

    • Use short and wide traces for power connections to minimize inductance and resistance.
    • Place bypass capacitors close to the input and output pins to improve stability and reduce noise.

12. Component Selection:

    • Choose external components (inductors, capacitors, resistors) based on the recommended values in the datasheet.
    • Verify the ratings of these components to ensure they can handle the expected currents and voltages.

13. Testing:

    • Test the circuit under various conditions to ensure it meets the design specifications.
    • Check for proper operation, stability, and efficiency.
