UCC28051DR Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC28051DR involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes, using a solid ground plane, and minimizing loop areas. TI provides a recommended layout in the datasheet and application notes.
  • Choose external components based on the specific requirements of your design, such as output voltage, current, and switching frequency. TI provides guidelines and equations in the datasheet and application notes to help with component selection.
  • The UCC28051DR has a maximum junction temperature of 150°C. Ensure reliable operation by providing adequate heat sinking, using a thermally conductive PCB material, and keeping the device within the recommended operating temperature range.
  • The UCC28051DR has a built-in overcurrent protection feature. Implement it by connecting a sense resistor (Rs) between the output inductor and the output capacitor, and adjusting the OCSET pin to set the overcurrent threshold.
  • The UCC28051DR is a dual-output controller, while the UCC28050DR is a single-output controller. The UCC28051DR also has a higher switching frequency range (up to 1.5 MHz) and a more comprehensive set of protection features.
