RT8299AZSP Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane and ensure good thermal conduction to the surrounding components.
  • Use a high-quality output capacitor with low ESR, ensure the input capacitor is properly decoupled, and add a 10nF capacitor between the FB pin and GND to reduce noise.
  • The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • The output voltage accuracy is typically ±2% over the entire operating range. Calculate the output voltage using the formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the feedback resistors.
  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close as possible to the VIN pin.
