LTC3780IUH#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LTC3780 can handle is 36V, but it's recommended to keep it below 32V for reliable operation.
-
The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
-
The SYNC pin is used to synchronize the switching frequency of multiple LTC3780 devices. To use it, connect the SYNC pins of multiple devices together, and set the switching frequency of one device as the master. The other devices will then synchronize their switching frequency to the master device.
-
The output voltage of the LTC3780 can be adjusted by changing the resistor divider ratio of the feedback resistors (RFB1 and RFB2). The output voltage is calculated using the formula: VOUT = 0.8V x (1 + RFB2/RFB1).
-
The maximum output current that the LTC3780 can deliver depends on the input voltage, output voltage, and inductor value. The datasheet provides a graph to determine the maximum output current based on these parameters.
