UCC28704DBVT-1 Frequently Asked Questions (FAQ)

  • A good PCB layout for the UCC28704DBVT-1 involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes, using a solid ground plane, and minimizing loop areas. TI provides a recommended layout in the datasheet and application notes.

  • Choose a transformer with a suitable turns ratio, core material, and winding configuration to match the UCC28704DBVT-1's operating frequency and power requirements. TI provides guidelines for transformer selection in the datasheet and application notes.

  • The maximum ambient temperature for the UCC28704DBVT-1 is 85°C, but the device can operate up to 125°C junction temperature. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.

  • The UCC28704DBVT-1 has a built-in overcurrent protection feature. Set the OCSET pin to the desired current limit, and the device will automatically shut down if the current exceeds this limit. You can also use external circuitry to enhance overcurrent protection.

  • The UCC28704DBVT-1 is designed for isolated converters, but it can also be used in non-isolated converters with proper design considerations. Ensure the device is properly configured and the output voltage is within the recommended range.
