UCC29910APWR Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the input and output stages. Keep the input and output traces short and away from each other to minimize noise and EMI.
  • Choose input capacitors with low ESR and high ripple current rating. Output capacitors should have low ESR and be rated for the output voltage. TI recommends using ceramic or film capacitors with X7R or X5R dielectrics.
  • The UCC29910APWR is rated for operation up to 85°C ambient temperature. However, derating the output power and ensuring good airflow can help maintain reliability at higher temperatures.
  • The UCC29910APWR has a built-in overcurrent protection feature. Connect a sense resistor (Rs) between the output and GND, and set the overcurrent threshold (Vocp) using an external resistor divider. The device will shut down when the output current exceeds the set threshold.
  • The recommended input voltage range is 12V to 18V. Operating outside this range may affect efficiency, output voltage regulation, and reliability.
