LM2678T-ADJ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2678T-ADJ is 40V, but it's recommended to keep it below 30V for reliable operation.
  • The output voltage of the LM2678T-ADJ can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
  • The minimum input voltage required for the LM2678T-ADJ to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2678T-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 LM2678T-ADJ from input voltage transients, a TVS diode or a transient voltage suppressor can be connected between the input and ground pins.
