LT3845EFE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3845EFE is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor.
  • The maximum output current that the LT3845EFE can deliver is 5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
  • The output voltage of the LT3845EFE can be programmed using the FB (feedback) pin and a resistive divider network. The output voltage is determined by the ratio of the resistors in the divider network.
  • The SS pin is used to control the soft-start function, which helps to reduce the inrush current during startup and prevents output voltage overshoot.
