LT8646SEV#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8646SEV#PBF can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and direct. Also, use a shielded inductor and orient it to minimize radiation.
  • The recommended PCB footprint for the LT8646SEV#PBF is a 4-layer board with a solid ground plane, and a thermal pad connected to a large copper area for heat dissipation.
  • Select an inductor with a high saturation current rating, low DCR, and a suitable inductance value based on the switching frequency and output voltage. A shielded inductor is recommended to minimize EMI.
  • The maximum output current that the LT8646SEV#PBF can deliver is 6A, but it's recommended to derate the output current based on the ambient temperature and the thermal design of the system.
