LM2594MX-ADJ/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2594 is 40V, but it's recommended to keep it below 35V for reliable operation.

  • The output voltage of the LM2594 can be set by using a resistive divider network between the output and the ADJ pin. The formula to calculate the output voltage is Vout = 1.23 x (1 + R2/R1).

  • The minimum input voltage required for the LM2594 to operate is 4V, but it's recommended to keep it above 5V for reliable operation.

  • No, the LM2594 is a buck converter and cannot be used as a boost converter. It's designed to step down the input voltage to a lower output voltage.

  • The inductor value for the LM2594 can be calculated using the formula L = (Vin - Vout) / (f x ΔI), where Vin is the input voltage, Vout is the output voltage, f is the switching frequency, and ΔI is the inductor ripple current.
