LTC3129EMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating above the peak current of the converter, and a DC resistance that minimizes power loss.
  • The RUN pin is an active-high enable input that allows the user to turn the converter on and off. To use it, simply tie the RUN pin to VIN or a logic-level signal to enable the converter, or tie it to GND to disable it.
  • To configure the LTC3129 for a specific output voltage, use the FB pin and a resistive divider network to set the output voltage. The FB pin is the feedback input, and the resistive divider network sets the output voltage based on the ratio of the resistors.
  • The maximum output current that the LTC3129 can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and thermal considerations.
