UCC28070DWR Frequently Asked Questions (FAQ)

  • A good PCB layout for the UCC28070DWR 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 to reduce EMI. 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 frequency. TI provides guidelines and recommendations for component selection in the datasheet and application notes. You can also use online tools and calculators to help with component selection.

  • Thermal management is crucial for the UCC28070DWR. Ensure good airflow, use a heat sink if necessary, and follow TI's guidelines for thermal pad connection and PCB layout. Monitor the device's junction temperature (TJ) and adjust the design as needed to prevent overheating.

  • To troubleshoot issues with your UCC28070DWR-based design, start by checking the basics: power supply, input voltage, and output voltage. Use an oscilloscope to visualize the waveforms and identify any anomalies. Consult TI's application notes and datasheet for troubleshooting guidelines and common pitfalls to avoid.

  • The enable pin (EN) controls the device's operation. During startup, ensure a clean and controlled enable signal to prevent unwanted switching. During shutdown, ensure a controlled disable sequence to prevent voltage spikes or oscillations. Consult the datasheet and application notes for specific guidelines.
