LTC3789IGN#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3789 is 40V, but it's recommended to keep it below 36V for reliable operation.
  • The inductor selection depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor selection guide provided in the datasheet, and then verify the inductor's saturation current, DC resistance, and core loss.
  • The SYNC pin is used to synchronize the switching frequency of multiple LTC3789 devices in a system. This is useful in applications where multiple converters need to operate in phase with each other to reduce EMI.
  • The output voltage of the LTC3789 is set by the resistive divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The maximum output current of the LTC3789 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.
