RT9193-33GB Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Ensure a minimum of 1 oz copper thickness and a thermal relief pattern under the IC.
  • Use a high-quality output capacitor with low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure the input capacitor is rated for the maximum input voltage.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the regulator's stability and output voltage regulation.
  • While ceramic capacitors are suitable for some applications, they may not be the best choice for the output capacitor due to their high ESR. A low-ESR electrolytic or polymer capacitor is recommended instead.
  • Calculate the power dissipation using the formula: Pd = (Vin - Vout) x Iout. Ensure the calculated power dissipation is within the maximum allowed power dissipation specified in the datasheet.
