LT3798IMSE#TRPBF Frequently Asked Questions (FAQs)

  • The LT3798 can handle input voltages up to 100V, but it's recommended to keep it below 80V 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-frequency nodes (e.g., SW node) away from sensitive analog nodes. 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 conduction to the PCB by using thermal vias and a heat sink (if necessary). Keep the IC away from other heat sources and ensure good airflow.
  • Choose an inductor with a high saturation current rating, low DCR, and a suitable inductance value (e.g., 1-10uH). Consider the inductor's physical size, core material, and operating frequency when selecting an inductor.
  • Use a low-ESR, high-frequency ceramic capacitor (e.g., X7R or X5R) with a value between 1-10uF, depending on the input voltage and desired ripple performance.
