LTC3889IUKG#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.
  • The compensation network can be optimized by following the guidelines in the datasheet and using the provided equations to calculate the values of the compensation components. Additionally, the LTC3889 demo board can be used as a reference design.
  • The TRACK/SS pin is used to track the output voltage during soft-start. It can be connected to an external voltage source or a resistor divider network to set the output voltage. The pin should be connected to a voltage source that is less than or equal to the output voltage.
  • The output voltage can be set by connecting a resistor divider network between the VOUT pin and the GND pin, and connecting the center tap of the divider to the FB pin. The ratio of the resistors determines the output voltage.
  • The maximum output current that the LTC3889 can deliver is 3.5A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
