RT9169-33GV Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The IC should be placed near a thermal pad or a heat sink to dissipate heat efficiently.
  • Ensure that the output capacitor has a low ESR and is placed close to the IC. Also, use a minimum of 10uF ceramic capacitor at the input pin to filter out noise and prevent oscillations.
  • The maximum input voltage is 18V, but it's recommended to keep it below 15V to ensure reliable operation and prevent damage to the IC.
  • The RT9169-33GV is rated for operation up to 85°C, but it's recommended to derate the output current and ensure good airflow to prevent overheating.
  • The output voltage ripple and noise can be calculated using the formula: ΔVout = (Iout x Rds(on) x fsw) / (Cout x Vout), where Iout is the output current, Rds(on) is the on-resistance of the internal switch, fsw is the switching frequency, Cout is the output capacitance, and Vout is the output voltage.
