LTC3115IFE-2#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 40V, but it's recommended to keep it below 36V for reliable operation.
  • The output voltage is set by the resistive divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The RUN pin is an active-high enable input that allows the user to turn the converter on and off. It can be connected to a logic signal or a switch to control the power-up and power-down sequence.
  • To ensure stability, it's recommended to add a soft-start capacitor (CSS) between the SS pin and GND, and to use a slow-rising input voltage during startup.
  • The maximum output current is 1.5A, but it's limited by the thermal performance of the package and the PCB design. The datasheet provides guidance on thermal management and layout considerations.
