Instructions for Using the ICE3BR4765JZ

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 180V to 600V.
   • Use appropriate input filtering and transient protection to avoid voltage spikes.

2. Output Voltage (VOUT):

   • The device is designed to provide a regulated output voltage of 5.0V.
   • Verify the output voltage using a multimeter to ensure it meets the required specifications.

3. Output Current (IOUT):

   • The device can provide a continuous output current of up to 2.0A.
   • For higher currents, consider additional heat sinking or derating the output.

4. Efficiency (η):

   • The typical efficiency is 92% under nominal conditions.
   • Monitor the efficiency to ensure optimal performance and minimal power loss.

5. Switching Frequency (fSW):

   • The fixed switching frequency is 65kHz.
   • This helps in designing the external components like inductors and capacitors.

6. Quiescent Current (IQ):

   • The typical quiescent current is 10mA.
   • This is the current drawn by the device when no load is applied.

7. Load Regulation (ΔVOUT/ΔIOUT):

   • The change in output voltage with load current should not exceed 1%.
   • Ensure that the load does not cause significant variations in output voltage.

8. Line Regulation (ΔVOUT/ΔVIN):

   • The change in output voltage with input voltage should not exceed 0.1%.
   • Maintain a stable input voltage to achieve consistent output.

9. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 1.0V to 1.5V at full load.
   • Ensure that the input voltage is always at least this much higher than the output voltage.

10. Thermal Shutdown Temperature (TSD):

    • The device will shut down if the temperature exceeds 160°C.
    • Implement proper thermal management to prevent overheating.

11. Operating Temperature Range (TOPR):

    • The device operates within an ambient temperature range of -40°C to 125°C.
    • Ensure the operating environment is within these limits.

12. Storage Temperature Range (TSTG):

    • The device can be stored at temperatures ranging from -65°C to 150°C.
    • Store the device in a dry and cool place to prevent damage.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Use recommended external components for optimal performance and reliability.
• Follow good PCB layout practices to minimize noise and interference.
