BA78M20FP-E2 Frequently Asked Questions (FAQs)

  • A thermal pad is recommended under the IC to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are also recommended.
  • Ensure that the input voltage is within the recommended range, and that the output capacitor is of sufficient value (at least 10uF) and ESR (less than 1 ohm) to maintain stability.
  • The maximum allowable ripple voltage on the input is 10% of the nominal input voltage, but it's recommended to keep it as low as possible to ensure stable operation.
  • While ceramic capacitors can be used, they may not provide the same level of stability as electrolytic capacitors due to their lower ESR. If used, ensure the ceramic capacitor has a high capacitance value (at least 22uF) and a low ESR (less than 1 ohm).
  • Use a voltage supervisor or a reset IC to monitor the input voltage and reset the device if it falls outside the recommended range. Additionally, consider using a TVS diode or a zener diode to protect against overvoltage conditions.
