Instructions for Use:

1. Input Voltage:

   • Ensure the input voltage is within the specified range (4.5V to 18V) to avoid damage to the device.

2. Output Voltage:

   • The output voltage is fixed at 5.0V. No external components are required for voltage adjustment.

3. Output Current:

   • The device can provide up to 2.0A of continuous output current, with typical performance at 1.5A.

4. Quiescent Current:

   • The quiescent current is typically 2.0mA and can go up to 3.0mA under no-load conditions.

5. Dropout Voltage:

   • The dropout voltage is typically 0.3V and can rise to 0.5V at maximum output current. Ensure the input voltage is at least 0.5V higher than the output voltage to maintain regulation.

6. Efficiency:

   • The device operates with typical efficiency of 92% under nominal conditions. Monitor the efficiency to ensure optimal performance.

7. Switching Frequency:

   • The switching frequency is set to 1.2MHz, which helps in reducing the size of external components like inductors and capacitors.

8. Load and Line Regulation:

   • The load regulation is ±1.0% and the line regulation is ±0.5%, ensuring stable output voltage over a wide range of operating conditions.

9. Ripple Rejection:

   • The power supply rejection ratio (PSRR) is 60dB at 100Hz, providing good noise immunity.

10. Operating and Storage Temperature:

    • The device can operate in temperatures ranging from -40°C to 125°C and can be stored between -55°C and 150°C.

11. Mounting and Layout:

    • Use a proper PCB layout to minimize noise and improve thermal performance. Place the input and output capacitors close to the device to reduce parasitic inductance.

12. Thermal Considerations:

    • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures. Consider using a heatsink if necessary.

13. Capacitors:

    • Use ceramic capacitors for both input and output filtering. Typical values are 10μF for input and 22μF for output.

14. Inductor Selection:

    • Choose an inductor with a saturation current rating higher than the maximum output current. A typical value is 4.7μH.

15. Protection Features:

    • The device includes overcurrent protection, thermal shutdown, and short-circuit protection to ensure safe operation.
