LT3791EFE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3791EFE is 100V, but it's recommended to keep it below 80V for reliable operation.
  • To ensure the LT3791EFE operates within its SOA, make sure to follow the guidelines in the datasheet for input voltage, output current, and junction temperature. Also, use the thermal derating curves to ensure the device doesn't overheat.
  • For optimal PCB layout, follow the guidelines in the datasheet and application notes. Keep the input and output capacitors close to the device, use a solid ground plane, and minimize trace lengths and loops. Also, consider using a shielded inductor and a common-mode choke to reduce EMI.
  • To select the right inductor, consider the output current, switching frequency, and inductor core material. Use the inductor selection guide in the datasheet and application notes to determine the optimal inductor value and type.
  • The SYNC pin allows the user to synchronize the switching frequency of the LT3791EFE with an external clock signal. This can be useful in noise-sensitive applications or when multiple converters need to be synchronized. To use the SYNC pin, connect it to an external clock signal with a frequency between 100kHz and 1MHz.
