LTC3789IUFD#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 32V, but it's recommended to keep it below 28V for reliable operation.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet, and then adjust based on the specific application requirements.
  • The SS pin is the soft-start pin, which allows the output voltage to ramp up slowly during startup. Connect a capacitor from the SS pin to GND to set the soft-start time, and adjust the capacitor value based on the desired startup time.
  • Output voltage ripple can be compensated for by adding a capacitor in parallel with the output capacitor, and adjusting the capacitor value based on the desired ripple attenuation.
  • The maximum output current that the LTC3789 can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
