LT3845EN#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3845EN is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output voltage is within the recommended range of 0.8V to 36V.
  • The maximum output current that the LT3845EN can deliver is 5A, but it's recommended to keep it below 4A for reliable operation and to prevent overheating.
  • The soft-start feature of the LT3845EN can be configured by connecting a capacitor between the SS pin and GND. The value of the capacitor determines the soft-start time, with a larger capacitor resulting in a longer soft-start time.
  • The SYNC pin on the LT3845EN is used to synchronize the switching frequency of multiple LT3845EN devices in a system. This can help to reduce EMI and improve system performance.
