Instructions for Use

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 36V.
   • Connect the input voltage to the VIN pin.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 5.0V.
   • Connect the output load to the VOUT pin.

3. Output Current (IOUT):

   • The maximum continuous output current is 1.5A, with a typical value of 1.0A.
   • Ensure the load does not exceed the maximum output current to avoid damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 80μA when the device is active.
   • This current is drawn from the input supply.

5. Shutdown Current (ISD):

   • When the device is in shutdown mode, the current draw is typically 1μA.
   • Use the SHDN pin to control the shutdown mode.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 1.0V at a 1.0A output current.
   • Ensure the input voltage is at least 1.0V higher than the output voltage to maintain regulation.

7. Switching Frequency (fSW):

   • The switching frequency is typically 1.5MHz.
   • This frequency can be adjusted using external components if needed.

8. Efficiency (η):

   • The efficiency is typically 85% at 12V input, 5V output, and 1A output current.
   • Optimize the design for maximum efficiency by minimizing losses in external components.

9. Thermal Shutdown (TSD):

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

10. Operating Junction Temperature (TJ):

    • The operating junction temperature range is -40°C to 125°C.
    • Ensure the device operates within this temperature range to avoid damage.

11. Storage Temperature Range (TSTG):

    • The storage temperature range is -65°C to 150°C.
    • Store the device in a controlled environment to prevent damage during storage.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Use appropriate decoupling capacitors on both the input and output to ensure stable operation.
• Ensure all connections are secure and free from shorts or open circuits.
