LM2670S-ADJ/NOPB Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2670S-ADJ/NOPB is 40V, but it's recommended to keep it below 35V for reliable operation.
-
The output voltage of the LM2670S-ADJ/NOPB can be adjusted by connecting a resistive 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 LM2670S-ADJ/NOPB to operate is 7.5V, but it's recommended to keep it above 8V for reliable operation.
-
The LM2670S-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 protect the LM2670S-ADJ/NOPB from input voltage transients, it's recommended to add a transient voltage suppressor (TVS) diode or a zener diode between the input and ground.
