LTC3129EUD#TRPBF 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 losses.
  • To minimize noise and EMI, keep the power stage components (L, C, and switches) close together, use a solid ground plane, and keep the feedback trace away from the power stage. Also, use a shielded inductor and orient it to minimize radiation.
  • The output voltage of the LTC3129 can be adjusted by changing the resistor divider ratio of the feedback network (RFBT and RFB B). Use the formula in the datasheet to calculate the required resistor values for the desired output voltage.
  • The RUN pin is an active-high enable input that allows the user to turn the converter on and off. Connect the RUN pin to VIN or a logic signal to enable or disable the converter.
