UCC21520DWR Frequently Asked Questions (FAQ)

  • A good PCB layout for the UCC21520DWR involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes, using a solid ground plane, and minimizing trace lengths and loop areas. TI provides a recommended PCB layout in the application note SLUA623.

  • To ensure reliable operation in high-temperature environments, ensure that the device is properly heatsinked, and the junction temperature (TJ) is kept below the maximum rating of 150°C. Also, consider derating the output current and voltage according to the thermal derating curve in the datasheet.

  • When selecting input and output capacitors for the UCC21520DWR, consider the capacitor's equivalent series resistance (ESR), voltage rating, and ripple current rating. TI recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the maximum input voltage and a ripple current rating that meets the application's requirements.

  • To troubleshoot issues with the UCC21520DWR, start by verifying the input voltage, output voltage, and current. Check for proper PCB layout, component selection, and thermal management. Use an oscilloscope to inspect the switching waveforms and identify any anomalies. Consult the datasheet and application notes for guidance on troubleshooting specific issues.

  • Yes, the UCC21520DWR can be used in a synchronous rectification topology. However, this requires careful design and layout considerations to ensure proper operation. TI provides guidance on synchronous rectification in the application note SLUA622.
