LT3991IMSE#PBF Frequently Asked Questions (FAQ)
-
The LT3991 can handle input voltages up to 60V, but it's recommended to operate within the 5.5V to 40V range for optimal performance.
-
To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the input capacitor.
-
The LT3991 can provide up to 1.5A of output current, but it's recommended to operate within the 1A range for optimal performance and thermal considerations.
-
The output voltage can be adjusted by using a resistive divider network between the output and the FB pin. The ratio of the resistors determines the output voltage.
-
The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
