UCC3806DW Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and placing the UCC3806DW close to the input capacitors and output inductors to minimize loop areas and reduce EMI. Additionally, TI suggests using a shielded inductor and placing it away from the UCC3806DW to reduce radiated emissions.
  • TI recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the maximum input voltage. For the output capacitor, TI suggests using a capacitor with a capacitance value of at least 10uF and a voltage rating of at least 1.5 times the maximum output voltage.
  • The maximum allowable voltage drop across the UCC3806DW's internal FETs is 1.5V. Exceeding this voltage drop may reduce the converter's efficiency and reliability.
  • The UCC3806DW's switching frequency can be adjusted by changing the value of the RT resistor connected to the RT pin. A higher switching frequency can reduce the size of the output filter components, but may increase EMI and reduce efficiency. A lower switching frequency can improve efficiency and reduce EMI, but may require larger output filter components.
  • TI recommends using a thermal pad or heat sink with a thermal resistance of less than 10°C/W to keep the junction temperature below 125°C. The UCC3806DW's thermal pad should be connected to a solid ground plane to improve heat dissipation.
