LM2591HVSX-ADJ Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2591HVSX-ADJ is 40V, but it's recommended to keep it below 37V to ensure reliable operation and to prevent damage to the internal circuitry.
-
The output voltage of the LM2591HVSX-ADJ can be set by connecting a resistor divider network between the output pin and the adjust pin. The formula to calculate the output voltage is Vout = 1.23V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
-
The minimum input voltage required for the LM2591HVSX-ADJ to operate is 4V, but it's recommended to keep it above 5V to ensure reliable operation and to prevent dropout.
-
The LM2591HVSX-ADJ is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C to ensure reliable operation and to prevent thermal shutdown.
-
To ensure the stability of the LM2591HVSX-ADJ output voltage, it's recommended to use a minimum output capacitance of 22uF, and to keep the output voltage ripple below 1% of the output voltage.
