LT8611IUDD#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT8611IUDD can handle?
  The maximum input voltage that the LT8611IUDD can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
• How do I optimize the layout for the LT8611IUDD to minimize EMI?
  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.
• What is the recommended input capacitor type for the LT8611IUDD?
  The recommended input capacitor type for the LT8611IUDD is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric, with a voltage rating of at least 50V.
• How do I select the right inductor for the LT8611IUDD?
  Select an inductor with a saturation current rating above the peak current, a low DCR, and a high SRF. The recommended inductor value is between 1.5uH and 3.3uH.
• What is the maximum ambient temperature range for the LT8611IUDD?
  The maximum ambient temperature range for the LT8611IUDD is -40°C to 125°C, but the junction temperature should not exceed 150°C.
