LM2679S-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 ADJ pin. The voltage is set by the ratio of the resistors, with a minimum voltage of 1.2V and a maximum voltage of 37V.
-
The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
-
The LM2679S-ADJ/NOPB is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. It's recommended to use a heat sink or thermal management system to keep the temperature within the operating range.
-
It's recommended to use a transient voltage suppressor (TVS) diode or a voltage clamp circuit to protect the LM2679S-ADJ/NOPB from input voltage transients and spikes.
