UCC28811DR Frequently Asked Questions (FAQs)

  • A good PCB layout for the UCC28811DR involves keeping the input and output stages separate, using a star-ground configuration, and placing the input filter components close to the IC. Additionally, using a solid ground plane and minimizing trace lengths can help reduce EMI.
  • When selecting a transformer for the UCC28811DR, consider the output power, voltage, and current requirements. Choose a transformer with a suitable turns ratio, core material, and wire size to ensure efficient energy transfer and minimize losses.
  • The UCC28811DR has a thermal pad that must be connected to a heat sink or a thermal plane on the PCB to dissipate heat. Ensure good thermal conductivity by using a thermal interface material and a heat sink with a suitable thermal resistance.
  • The UCC28811DR has a built-in overcurrent protection feature that can be enabled by connecting the OC pin to a resistor divider network. This allows the IC to detect overcurrent conditions and shut down the output to prevent damage.
  • To minimize EMI, use a pi-filter configuration with a common-mode choke, capacitors, and resistors to filter the input and output stages. Ensure that the filter components are placed close to the IC and that the PCB layout is optimized for EMI reduction.
