LM2577T-ADJ Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LM2577T-ADJ is 40V, but it's recommended to keep it below 35V for reliable operation.
-
The output voltage of the LM2577T-ADJ can be set by connecting a resistor divider network between the output and the ADJ pin. The formula to calculate the output voltage is: Vout = 1.23 x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
-
The minimum input voltage required for the LM2577T-ADJ to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
-
The LM2577T-ADJ 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 ensure the stability of the LM2577T-ADJ output voltage, it's recommended to use a minimum output capacitance of 22uF and to keep the output voltage ripple below 1%.
