LTC3417AEDHC-2#PBF datasheet by Linear Technology

LTC3417AEDHC-2#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3417AEDHC-2#PBF can handle?
  The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
• How do I optimize the layout for the LTC3417AEDHC-2#PBF to minimize EMI and noise?
  Keep the input and output capacitors close to the IC, use a solid ground plane, and minimize the length of the high-current paths. Also, consider using a shielded inductor and placing it away from sensitive components.
• What is the recommended inductor value and type for the LTC3417AEDHC-2#PBF?
  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. The inductor type should be a high-current, low-loss inductor with a high saturation current rating.
• How do I adjust the output voltage of the LTC3417AEDHC-2#PBF?
  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.
• What is the maximum output current that the LTC3417AEDHC-2#PBF can deliver?
  The maximum output current is 1.5A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
