UCC3818AD datasheet by Texas Instruments

UCC3818AD Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the UCC3818AD to minimize EMI and noise?
  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.
• How do I optimize the compensation network for the UCC3818AD?
  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.
• What is the maximum allowed input voltage for the UCC3818AD?
  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.
• Can I use the UCC3818AD in a synchronous rectification topology?
  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.
• How do I troubleshoot and debug issues with the UCC3818AD?
  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.
