UCC27528D Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC27528D involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes, using a solid ground plane, and minimizing trace lengths and loops. TI provides a recommended layout in the datasheet and application notes.
  • The inductor value depends on the input voltage, output voltage, and desired switching frequency. A good starting point is to use the inductor selection guide in the datasheet, and then fine-tune the value based on the specific application requirements and efficiency goals.
  • The maximum TJ for the UCC27528D is 150°C. However, it's recommended to keep TJ below 125°C for reliable operation and to ensure a long device lifespan.
  • Yes, the UCC27528D can be used in a synchronous rectification topology. In fact, it's designed to work with an external FET for synchronous rectification, which can improve efficiency and reduce power losses.
  • The UCC27528D has a built-in voltage regulator, and compensation is required for stability. TI provides a compensation calculator and guidelines in the datasheet and application notes to help designers achieve stable operation.
