LT3991EDD#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage is 60V, but it's recommended to keep it below 50V for optimal performance and reliability.
-
To ensure stability, make sure to use the recommended output capacitor values and types, and keep the output voltage within the specified range (1.2V to 15V).
-
The maximum output current is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.
-
The output voltage can be adjusted by using a resistive divider network between the VOUT pin and the GND pin, and connecting the feedback pin (FB) to the center tap of the divider.
-
The EN (enable) pin is used to turn the regulator on or off. When EN is high, the regulator is enabled, and when EN is low, the regulator is disabled.
