LTC3115MPFE-1#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 losses.
  • For optimal performance, keep the high-current paths short and wide, and separate the input and output grounds. Place the input capacitors close to the VIN pin, and the output capacitors close to the VOUT pin. Use a solid ground plane and avoid routing high-frequency signals under the IC.
  • The output voltage of the LTC3115 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 a logic-level signal source, such as a microcontroller output, to control the converter's operation.
