LT3991IMSE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT3991IMSE is 60V, but it's recommended to operate within the specified input voltage range of 7V to 40V for optimal performance.
-
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor.
-
The maximum output current that the LT3991IMSE can deliver is 1.5A, but it's recommended to operate within the specified output current range of 0A to 1.2A for optimal performance and reliability.
-
The output voltage of the LT3991IMSE can be adjusted by using a resistive divider network between the output and the feedback pin, allowing for a wide range of output voltage options.
-
The EN (enable) pin on the LT3991IMSE is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled, allowing for power-saving and shutdown capabilities.
