UCC3806PW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with short traces, and placing the UCC3806PW close to the power stage. Additionally, a solid ground plane and a separate analog ground plane can help reduce EMI and noise. Refer to the TI application note 'UCC3806PW Layout and Placement Guidelines' for more details.
  • The recommended value for the VCC bypass capacitor is 1-10uF, with a voltage rating of at least 10V. A larger capacitor value can help reduce noise and improve stability, but may increase the startup time. A good starting point is a 2.2uF capacitor, and adjust as needed based on the specific application.
  • The maximum allowed voltage on the VCC pin is 15V, but it's recommended to keep it below 12V for reliable operation. Exceeding the maximum voltage can cause damage to the device or affect its performance.
  • The switching frequency of the UCC3806PW can be adjusted by changing the value of the RT resistor connected to the RT pin. A smaller RT resistor value increases the switching frequency, while a larger value decreases it. Refer to the datasheet for the recommended RT resistor values and calculation formula.
  • The bootstrap capacitor (CB) is used to generate the high-side gate drive voltage. The recommended value for CB is 10-100nF, with a voltage rating of at least 10V. A larger capacitor value can help improve the high-side gate drive voltage, but may increase the startup time.
