UCC28711DR Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC28711DR 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 turns ratio that matches the desired output voltage, and ensure it can handle the maximum primary current. Consider factors like core material, winding resistance, and leakage inductance. TI provides guidelines for transformer selection in the datasheet and application notes.
  • The UCC28711DR is rated for operation up to 105°C ambient temperature, but derating may be necessary for high-power applications or high-temperature environments. Consult the datasheet for thermal derating curves.
  • The UCC28711DR has a built-in overcurrent protection (OCP) feature. Set the OCP threshold by selecting the correct resistor value for the ROC pin. The device will shut down if the current exceeds the set threshold. Consult the datasheet for OCP calculation and implementation details.
  • Yes, the UCC28711DR is suitable for isolated DC-DC conversion applications, such as flyback converters. Ensure proper transformer design and layout to maintain isolation and meet safety standards.
