Instructions for Use

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 60V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage (VOUT):

   • Set the output voltage between 0.8V and 30V using the feedback resistor network.
   • Use the formula ( V_ = 1.25 left(1 + fracright) ) to calculate the resistor values.

3. Output Current (IOUT):

   • The typical output current is 1.5A, with a maximum of 3A.
   • Ensure the load does not exceed the maximum output current to avoid overheating.

4. Efficiency:

   • The efficiency is typically 90% at VOUT = 5V, VIN = 12V, and IOUT = 1A.
   • Optimize the circuit design to maintain high efficiency.

5. Switching Frequency (fSW):

   • The switching frequency is typically 650kHz.
   • Adjust the external components if a different frequency is required.

6. Quiescent Current (IQ):

   • The quiescent current is typically 50μA when no load is applied.
   • This value helps in power budget calculations for low-power applications.

7. Load Regulation:

   • The load regulation is typically 0.5% for VOUT = 5V, VIN = 12V, and IOUT = 0 to 1.5A.
   • Ensure the output voltage remains stable under varying load conditions.

8. Line Regulation:

   • The line regulation is typically 0.2% for VOUT = 5V, IOUT = 1A, and VIN = 4.5 to 60V.
   • Maintain stable output voltage with changes in input voltage.

9. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 1.2V at IOUT = 1A and VOUT = 5V.
   • Ensure the input voltage is sufficiently higher than the output voltage to avoid dropout.

10. Thermal Shutdown (TSD):

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

11. Operating Temperature (TOPR):

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

12. Storage Temperature (TSTG):

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