LTC3643IUDD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.
  • The maximum output current that the LTC3643 can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • The output voltage can be programmed using the FB pin. Connect a resistive divider from the output voltage to the FB pin, and adjust the resistors to set the desired output voltage.
  • The RUN pin is an active-high enable input that allows the user to turn the regulator on and off. When the RUN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
