UCC28633D Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the UCC28633D evaluation module (EVM) user's guide, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The UCC28633D datasheet provides guidelines for transformer selection, including recommended turns ratios, inductance values, and core materials. Additionally, Texas Instruments offers a transformer selection tool on their website to help designers choose the right transformer for their specific application.
  • While the datasheet specifies an operating temperature range of -40°C to 125°C, the device can operate up to 150°C with derating. However, it's essential to consider the thermal management of the system and ensure that the device does not exceed the maximum junction temperature (Tj) of 150°C.
  • The UCC28633D has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values. Texas Instruments provides an application note (SLUAAC3) that provides more details on implementing OVP with the UCC28633D.
  • The UCC28633D datasheet recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF for the input capacitor. The capacitor type and value may need to be adjusted based on the specific application requirements and input voltage ripple.
