LM22679TJ-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM22679TJ-ADJ/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • The output voltage of the LM22679TJ-ADJ/NOPB can be adjusted by connecting a resistor divider network between the output and the ADJ pin, and then connecting the center tap of the divider to the ADJ pin.
  • The minimum input capacitance required for the LM22679TJ-ADJ/NOPB is 10uF, but it's recommended to use a higher value (e.g. 22uF) for better performance and stability.
  • The LM22679TJ-ADJ/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.
  • To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient input capacitance, and avoid high-frequency noise on the input and output lines.
