UCC3808AD-1 Frequently Asked Questions (FAQs)

  • It is recommended to place the UCC3808AD-1 close to the power stage, use a solid ground plane, and keep the high-frequency loops small. Additionally, use a shielded cable for the current sense lines and keep them away from noisy signals.
  • The voltage drop across the current sense resistor can be compensated for by adding an offset voltage to the current sense signal or by using a sense resistor with a low voltage drop.
  • The maximum allowed voltage on the VCC pin is 15V, but it is recommended to keep it below 12V for reliable operation.
  • Ensure that the VCC pin is properly biased between 8V and 12V, and the voltage on the VREF pin is set to 2.5V or 4.5V depending on the application.
  • The recommended frequency range for the oscillator circuit is between 50 kHz and 500 kHz, but it can be adjusted based on the specific application requirements.
