LT8491EUKJ#PBF Frequently Asked Questions (FAQs)

  • The LT8491 can handle input voltages up to 40V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To minimize EMI and noise, 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 between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5Ω) is recommended to minimize losses and EMI.
  • 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 LT8491 can deliver up to 2A of output current, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
