UCC35701D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the UCC35701D?
  A good PCB layout for the UCC35701D involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. TI provides a recommended PCB layout in the datasheet and application notes.
• How do I ensure the UCC35701D is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended component values and PCB layout. Additionally, ensure that the input and output capacitors are of high quality and have low ESR. Also, avoid using long wires or traces for the feedback loop.
• What is the maximum ambient temperature range for the UCC35701D?
  The UCC35701D is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may be limited by the specific application and the thermal design of the system.
• Can I use the UCC35701D in a synchronous rectification topology?
  Yes, the UCC35701D can be used in a synchronous rectification topology. However, it requires additional external components and careful design to ensure proper operation.
• How do I calculate the minimum input voltage required for the UCC35701D?
  The minimum input voltage required for the UCC35701D depends on the output voltage, output current, and efficiency requirements. A general rule of thumb is to ensure that the input voltage is at least 2-3V higher than the output voltage.
