SLR343BC4T3F Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC, and a 2-layer or 4-layer PCB with a thermal relief pattern is suggested to improve heat dissipation.
  • Use a high-quality output capacitor with low ESR, ensure a stable input voltage, and minimize noise on the VIN pin to ensure stable output voltage regulation.
  • The maximum allowed input voltage ripple is 10% of the input voltage, but it's recommended to keep it below 5% to ensure stable operation.
  • While ceramic capacitors can be used, they may cause oscillation due to their low ESR. A tantalum or electrolytic capacitor with low ESR is recommended for the output capacitor.
  • Calculate the power dissipation using the formula: Pd = (VIN - VOUT) x IOUT. Ensure the calculated power dissipation is within the specified maximum power dissipation of the IC.
