LM2640MTCX-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2640MTCX-ADJ/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
  • The output voltage of the LM2640MTCX-ADJ/NOPB can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The ratio of the resistors determines the output voltage.
  • The minimum input voltage required for the LM2640MTCX-ADJ/NOPB to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2640MTCX-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, it's recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 10uF with an ESR of 0.1 ohm or less.
