UCC21750DW Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC21750DW 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.
  • When selecting a transformer for the UCC21750DW, consider the maximum output power, output voltage, and input voltage. The transformer's turns ratio, inductance, and core material should be chosen to ensure efficient energy transfer. TI provides guidelines for transformer selection in the application note SLUA622.
  • The maximum junction temperature for the UCC21750DW is 150°C. It's essential to ensure that the device operates within this temperature range to prevent overheating and ensure reliable operation.
  • The UCC21750DW has a built-in overcurrent protection feature. To implement it, connect a sense resistor (Rs) in series with the output inductor. The device will detect the voltage across Rs and shut down if the current exceeds the programmed threshold.
  • While the UCC21750DW is primarily designed for isolated topologies, it can be used in non-isolated configurations with some modifications. However, this may require additional components and careful design considerations to ensure safe and reliable operation.
