RT4803WSC Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the component side of the PCB clear of copper to minimize thermal resistance.
  • Use a high-quality input capacitor with low ESR, and ensure the output capacitor is sufficient for the desired output voltage ripple. Also, consider adding a voltage feed-forward capacitor to improve transient response.
  • The maximum allowable ripple current is typically 20-30% of the input capacitor's rated current. Exceeding this may reduce the capacitor's lifespan.
  • Yes, but ensure the ceramic capacitor is rated for the output voltage and has a low ESR. X5R or X7R dielectrics are recommended. Avoid using Y5V or Z5U dielectrics due to their high ESR and voltage coefficient.
  • Use the formula: C_in = (I_out * ΔV_out) / (f_sw * ΔV_in), where I_out is the output current, ΔV_out is the output voltage ripple, f_sw is the switching frequency, and ΔV_in is the input voltage ripple.
