LTC3787MPUFD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3787 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 above the maximum output current.
  • The SYNC pin allows the user to synchronize the switching frequency of the LTC3787 with an external clock signal, which can be useful in noise-sensitive applications or when multiple converters need to be synchronized.
  • The output voltage of the LTC3787 can be set using the FB pin and a resistive divider network. The FB pin is connected to the output voltage through a resistive divider, and the ratio of the resistors determines the output voltage.
  • The maximum output current that the LTC3787 can deliver depends on the input voltage, output voltage, and inductor selection. The datasheet specifies a maximum output current of 2A, but this can be limited by the inductor saturation current and thermal considerations.
