LT3475EFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3475EFE is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To ensure the stability of the output voltage, it's essential to use the recommended output capacitor values and types, and to follow the layout guidelines provided in the datasheet.
  • The maximum output current that the LT3475EFE can deliver is 2A per channel, but it's recommended to derate the current based on the ambient temperature and the desired reliability.
  • To synchronize the switching frequencies of multiple LT3475EFE devices, connect the SYNC pin of each device to a common clock signal, and ensure that the clock frequency is within the recommended range of 200kHz to 400kHz.
  • The EN/UVLO pin is used to enable or disable the device, and to set the undervoltage lockout (UVLO) threshold. When the input voltage falls below the UVLO threshold, the device shuts down to prevent damage.
