UCC21750DWR Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC21750DWR 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 application note SLUA623.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value. The inductor value depends on the input voltage, output voltage, and switching frequency. TI provides an inductor selection guide in the application note SLUA623.
  • The maximum ambient temperature for the UCC21750DWR is 85°C. However, the device can operate up to 105°C with derating. Refer to the datasheet for thermal derating curves.
  • The UCC21750DWR has a built-in overcurrent protection feature. Connect a sense resistor (Rs) between the VIN pin and the source of the power FET. The device will shut down if the current through Rs exceeds the overcurrent threshold (typically 2.5 A).
  • Yes, the UCC21750DWR can be used in a synchronous rectification configuration. This requires an external FET and a diode, and the device's SYNC pin should be connected to the drain of the synchronous FET.
