Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 28V.
   • Do not exceed the maximum input voltage to avoid damaging the device.

2. Output Voltage (VOUT):

   • Set the output voltage using the external feedback resistor network.
   • The output voltage can be adjusted from 0.8V to 20V.

3. Output Current (IOUT):

   • The device can provide up to 3A of output current, with a typical output current of 2.5A.
   • Ensure that the load does not exceed the maximum output current to prevent overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 100μA and should not exceed 200μA.
   • This parameter is important for low-power applications.

5. Efficiency (η):

   • The typical efficiency is 92%, which is achieved under optimal conditions.
   • Efficiency may vary depending on the load and input voltage.

6. Switching Frequency (fSW):

   • The switching frequency is fixed at 600kHz.
   • This frequency helps in minimizing the size of external components like inductors and capacitors.

7. Soft-Start Time (tSS):

   • The soft-start time is typically 2.5ms, which helps in reducing inrush current during startup.
   • This can be adjusted if necessary by modifying the external capacitor value.

8. Thermal Shutdown (TSD):

   • The device will automatically shut down if the internal temperature exceeds 160°C.
   • Ensure proper heat dissipation to prevent thermal shutdown.

9. Operating Temperature (TOPR):

   • The operating temperature range is from -40°C to 125°C.
   • Ensure that the device operates within this range to maintain reliability.

10. Storage Temperature (TSTG):

    • The storage temperature range is from -55°C to 150°C.
    • Store the device in a dry and cool environment to prevent damage.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Use appropriate external components (inductors, capacitors, resistors) as specified in the datasheet to ensure optimal performance.
