LTC3789EUFD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3789EUFD is 40V, but it's recommended to keep it below 36V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input capacitor.
  • The maximum output current that the LTC3789EUFD can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
  • To configure the LTC3789EUFD for a specific output voltage, use the feedback resistors R1 and R2 to set the output voltage. The ratio of R1 to R2 determines the output voltage.
  • The EN (enable) pin is used to turn the converter on and off. When EN is high, the converter is enabled, and when EN is low, the converter is disabled.
