LM22670TJE-ADJ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM22670TJE-ADJ is 42V, but it's recommended to keep it below 40V for reliable operation.
  • The output voltage of the LM22670TJE-ADJ 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 voltage required for the LM22670TJE-ADJ to operate is 7.2V, but it's recommended to keep it above 8V for reliable operation.
  • The LM22670TJE-ADJ 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 protect the LM22670TJE-ADJ from input voltage transients, it's recommended to add a TVS diode or a transient voltage suppressor between the input and ground, and also to add a capacitor between the input and ground to filter out high-frequency noise.
