LM22678TJ-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (4.5V to 5.5V).
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
  • The LM22678TJ-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation.
  • The output current capability can be calculated using the formula: Iout = (Vin - Vout) / Rds(on) x Efficiency, where Rds(on) is the on-resistance of the internal switch and Efficiency is the converter's efficiency.
