LTC3780IUH#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3780IUH is 36V, but it's recommended to keep it below 30V for reliable operation.
-
The inductor selection depends on the output current, switching frequency, and output voltage. A good starting point is to use an inductor with a value between 1.5uH to 3.3uH, and a saturation current rating of at least 1.5 times the maximum output current.
-
The SYNC pin is used to synchronize the switching frequency of multiple LTC3780IUH devices in a system. It can also be used to synchronize the switching frequency with an external clock signal.
-
The output voltage of the LTC3780IUH is set by the resistive divider network connected to the FB pin. The ratio of the resistors determines the output voltage, and the datasheet provides a formula to calculate the required resistor values.
-
The maximum output current of the LTC3780IUH depends on the input voltage, output voltage, and inductor selection. The datasheet provides a graph to determine the maximum output current based on these parameters.
