UCC3818AD Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and placing the UCC3818AD close to the input capacitors and output inductors to minimize loop areas and reduce EMI. Additionally, use a shielded inductor and keep the feedback trace away from the power traces.
  • Use TI's WEBENCH Power Designer tool to generate a compensation network based on the specific application requirements. Alternatively, use the datasheet's compensation network design equations and adjust the values based on the target output voltage and load current.
  • The maximum allowed input voltage for the UCC3818AD is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize the risk of damage.
  • Yes, the UCC3818AD can be used in a synchronous rectification topology, but it requires additional external components and careful design to ensure proper operation and minimize losses.
  • Use an oscilloscope to monitor the input and output voltages, and check for signs of oscillation or instability. Verify the component values and PCB layout, and consult the datasheet and application notes for troubleshooting guides and common pitfalls.
