LM2676S-ADJ/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.

  • The output voltage 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 is 7.5V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2676S-ADJ/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current at high temperatures to prevent overheating.

  • You can add a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor to protect the regulator from input voltage surges.
