LT3690EUFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3690EUFE 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.
  • Use a 2-4 layer PCB with a solid ground plane, and ensure good thermal conductivity between the IC and the PCB. Use thermal vias to connect the IC's thermal pad to the ground plane, and consider using a heat sink or thermal interface material for high-power applications.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (typically 1-10uH). Consider the inductor's physical size, core material, and operating frequency when selecting the right inductor for your application.
  • The maximum output current that the LT3690EUFE can deliver is 3.5A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
