Instructions:

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 damage.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 5V. No external components are required for voltage adjustment.

3. Output Current (IOUT):

   • The device can provide up to 5A of continuous output current.
   • Ensure that the load does not exceed this limit to prevent overheating or damage.

4. Efficiency:

   • The typical efficiency is 93% under standard operating conditions (3.3V IN, 5V OUT, 1A Load).
   • Efficiency may vary with different input voltages and load conditions.

5. Switching Frequency (fSW):

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

6. Quiescent Current (IQ):

   • The quiescent current is typically 2.5mA.
   • This is the current drawn by the device when it is active but not supplying any load.

7. Shutdown Current (ISD):

   • The shutdown current is typically 1μA.
   • Use the shutdown pin to turn off the device when not in use to save power.

8. Operating Temperature (TOPR):

   • The device can operate in temperatures ranging from -40°C to 85°C.
   • Ensure proper heat dissipation if operating near the upper temperature limit.

9. Storage Temperature (TSTG):

   • Store the device in temperatures ranging from -40°C to 125°C.
   • Avoid exposing the device to extreme temperatures for extended periods.

10. Mounting and Layout:

    • Follow recommended PCB layout guidelines to ensure optimal performance and thermal management.
    • Use appropriate heatsinks or thermal vias if necessary to dissipate heat effectively.

11. Safety Precautions:

    • Always handle the device with care to avoid static discharge.
    • Ensure all connections are secure and correctly wired to prevent short circuits or other electrical issues.
