Instructions for UCC28600DR

1. Power Supply Connection:

   • Connect the input power supply to the designated pins ensuring it is within the operating voltage range of 10V to 75V.

2. Setting the Switching Frequency:

   • Adjust the external resistor connected to the RT/CT pin to set the desired switching frequency between 65kHz and 300kHz.

3. Output Configuration:

   • Configure the output stage according to the maximum output power requirement (up to 400W).

4. Efficiency Optimization:

   • For optimal efficiency, operate the device under conditions that allow it to achieve its typical efficiency of 92%.

5. Protection Circuits:

   • Ensure all protection features (overcurrent, overvoltage, undervoltage lockout, and thermal shutdown) are properly configured and tested.

6. Quiescent Current Consideration:

   • Be mindful of the quiescent current of 0.3mA when designing low-power applications.

7. Thermal Management:

   • Implement adequate heat dissipation methods to prevent overheating and ensure reliable operation.

8. Refer to Datasheet:

   • Always refer to the detailed datasheet for more specific parameters and application notes.
