Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 100V to 265V AC.
   • Use appropriate input filtering and transient protection.

2. Output Voltage (VOUT):

   • Set the output voltage using the feedback network.
   • Verify the output voltage with a multimeter before connecting the load.

3. Output Current (IOUT):

   • The maximum output current is 1.5A. Design the power supply to handle this current safely.
   • Use a heatsink if the output current is near the maximum to ensure proper heat dissipation.

4. Switching Frequency (fSW):

   • The switching frequency can be set between 65kHz and 130kHz using an external resistor.
   • Higher frequencies reduce the size of external components but increase switching losses.

5. Power Dissipation (PD):

   • The maximum power dissipation is 7.2W. Ensure adequate cooling to prevent overheating.
   • Use a heatsink or forced air cooling if necessary.

6. Efficiency (η):

   • The typical efficiency is 85%. Optimize the design to achieve this efficiency.
   • Minimize losses by selecting high-efficiency components and optimizing the PCB layout.

7. Operating Temperature (Toper):

   • The operating temperature range is -40°C to 85°C.
   • Avoid exposing the device to temperatures outside this range to prevent damage.

8. Storage Temperature (Tstg):

   • The storage temperature range is -55°C to 150°C.
   • Store the device in a dry, cool place to ensure long-term reliability.

9. Junction Temperature (TJ):

   • The junction temperature should not exceed 150°C.
   • Monitor the junction temperature during operation to ensure it remains within safe limits.

10. Thermal Resistance (θJA):

    • The typical thermal resistance is 50°C/W.
    • Use a heatsink or other cooling methods to reduce the thermal resistance and improve heat dissipation.

Additional Notes:

• Always refer to the datasheet for detailed specifications and application notes.
• Follow good PCB layout practices to minimize noise and ensure stable operation.
• Test the power supply under all expected operating conditions to verify performance and reliability.
