LTC3789EUFD#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.
  • 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, ensure that the output voltage is within the recommended range of 0.8V to 15V.
  • The RUN pin is an active-high enable input that allows the user to turn the converter on and off. To use it, simply tie the RUN pin to VIN to enable the converter, or tie it to GND to disable it.
  • To calculate the inductor value, use the following formula: L = (VIN * (1 - D)) / (f * ΔI), where L is the inductor value, VIN is the input voltage, D is the duty cycle, f is the switching frequency, and ΔI is the inductor ripple current.
  • The maximum output current that the LTC3789EUFD can deliver is 2A, but it's recommended to keep it below 1.5A for reliable operation.
