LT8705EUHF#TRPBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the high-current paths.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure the input voltage rises slowly (e.g., using a soft-start capacitor). For shutdown, use a voltage supervisor to ensure the converter is fully disabled before the input voltage drops.
  • The maximum ambient temperature for reliable operation is 85°C, but this can be derated based on the specific application and thermal design. Ensure good airflow and heat sinking to maintain a safe junction temperature.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Ensure good PCB layout and decoupling to minimize radiation.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22μF, depending on the input voltage and ripple requirements. Ensure the capacitor is rated for the maximum input voltage.
