UCC3808N-2G4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with short traces, and placing the IC close to the power stage. Additionally, a solid ground plane and a separate analog ground plane can help reduce noise and EMI. Refer to the application note SLUA271 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.
  • The maximum allowed voltage on the VCC pin is 15V, but it's recommended to keep it below 12V for reliable operation. Exceeding this voltage can cause damage to the IC.
  • The switching frequency can be adjusted by changing the value of the RT resistor connected to the RT pin. A smaller resistor value increases the switching frequency, while a larger value decreases it. Refer to the datasheet for the recommended RT resistor values.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. The recommended value for CBOOT 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.
