LT8631EFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8631EFE 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 wide. Also, avoid routing sensitive signals near the inductor.
  • The recommended inductor value is 2.2μH to 4.7μH, and a shielded inductor with a low DCR (e.g., 0.5Ω to 1Ω) is recommended for optimal performance.
  • The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V x (1 + R2/R1) to calculate the desired output voltage.
  • The maximum output current that the LT8631EFE can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
