LTC3784IGN#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3784 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 LTC3784 devices in a system. It can also be used to synchronize the switching frequency with an external clock signal.
  • The output voltage of the LTC3784 can be configured by selecting the appropriate resistors for the feedback network (RFBT and RFB) and the voltage divider network (R1 and R2). The datasheet provides a formula to calculate the required resistor values.
  • The maximum output current that the LTC3784 can deliver depends on the input voltage, output voltage, and inductor selection. The datasheet provides a graph to determine the maximum output current based on the input voltage and output voltage.
