The recommended layout and placement for the UCC3813D-3 involves keeping the input and output stages separate, using a star-ground configuration, and placing the device close to the power source. TI provides a layout guide in the application note SLUA121.
Choosing the right transformer involves considering factors such as the turns ratio, magnetizing inductance, and leakage inductance. TI provides a transformer selection guide in the application note SLUA122.
The maximum power rating of the UCC3813D-3 is dependent on the specific application and operating conditions. However, as a general guideline, the device can handle up to 100W of output power. It's recommended to consult the datasheet and application notes for more detailed information.
The UCC3813D-3 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OC pin and the GND pin. The value of the resistor determines the overcurrent threshold. TI provides more detailed information on implementing overcurrent protection in the application note SLUA123.
The recommended operating temperature range for the UCC3813D-3 is -40°C to 85°C. However, the device can operate up to 125°C with derating. It's recommended to consult the datasheet for more detailed information on temperature derating.
