LT3991EMSE-5#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage is 60V, but it's recommended to keep it below 50V for reliable operation.
-
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 reliable operation and to prevent overheating.
-
The output voltage can be calculated using the formula: Vout = (R1/R2) * (1.2V), where R1 and R2 are the resistors used in the feedback network.
-
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.
