LTC3891HUDC#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 LTC3891 demo board can be used as a reference design.
  • The maximum output current that the LTC3891 can deliver is 1.5A per phase, but it's recommended to derate the output current based on the ambient temperature and the thermal design of the system.
  • The switching frequency of multiple LTC3891 devices can be synchronized by connecting the SYNC pin of each device to a common clock signal. The clock signal should be within the recommended frequency range of 250kHz to 2MHz.
  • The TRACK/SS pin is used to track the output voltage during soft-start or to implement a power-good function. It can be connected to an external voltage source or a resistive divider to track the output voltage.
