LT3845AIFE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3845AIFE 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 LT3845AIFE can deliver is 5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage.
  • To synchronize the switching frequency, connect the SYNC pin of each device to a common clock signal, and ensure that the clock frequency is within the recommended range of 250 kHz to 2.2 MHz.
  • The SS pin is used to program the soft-start time of the device. A capacitor connected between the SS pin and GND sets the soft-start time, which helps to reduce inrush current during startup.
