LTC3121IDE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance.
  • To optimize 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 drawn by 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, connect the RUN pin to a logic-level signal (e.g., from a microcontroller) to enable or disable the converter.
  • To configure the LTC3121 for a specific output voltage, use the FB pin and an external resistor divider network to set the output voltage. The FB pin is connected to the output voltage through a resistor divider, and the ratio of the resistors determines the output voltage.
  • The maximum output current that the LTC3121 can deliver is 2A, but this can be limited by the input voltage, inductor selection, and thermal considerations.
