LT3690HUFE#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT3690HUFE is 42V, but it's recommended to keep it below 40V for reliable operation.
-
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 LT3690HUFE can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
-
The soft-start feature of the LT3690HUFE can be configured by connecting a capacitor from the SS pin to ground. The value of the capacitor determines the soft-start time, with a larger capacitor resulting in a longer soft-start time.
-
The EN (enable) pin on the LT3690HUFE is used to turn the device on or off. When the EN pin is high, the device is enabled, and when it's low, the device is disabled.
