LT3481EDD#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT3481EDD#PBF can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
-
To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output voltage is within the recommended range of 0.8V to 15V.
-
The maximum output current that the LT3481EDD#PBF can provide is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and reliability.
-
The soft-start feature of the LT3481EDD#PBF can be configured by connecting a capacitor from the SS pin to GND. The value of the capacitor determines the soft-start time, with a larger capacitor resulting in a slower soft-start.
-
The EN (enable) pin on the LT3481EDD#PBF is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
