LTC3785IUF#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3785 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 an inductor with an inductance value between 1uH to 10uH, and a saturation current rating higher than the peak current drawn by the converter.
  • The SYNC pin is used to synchronize the switching frequency of multiple LTC3785 devices in a system, allowing them to operate in phase and reducing electromagnetic interference (EMI).
  • The output voltage of the LTC3785 can be set using the FB pin and a resistive divider network. The resistors should be chosen such that the voltage at the FB pin is equal to the desired output voltage divided by the feedback voltage (0.8V).
  • The maximum output current of the LTC3785 depends on the input voltage, output voltage, and inductor selection. The device can deliver up to 2A of output current, but it's recommended to derate the current based on the thermal performance of the system.
