LTC4162IUFD-FAD#PBF 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 power paths. Avoid routing sensitive analog signals near the switching node.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a high self-resonant frequency. The inductor value should be between 1.5uH to 3.3uH, and the recommended inductor types are shielded or unshielded ferrite or iron powder cores.
  • The maximum ambient temperature range for the LTC4162IUFD-FAD#PBF is -40°C to 125°C. However, the device can operate up to 150°C with derating.
  • Use a shielded inductor, keep the layout compact, and use a common-mode choke to reduce EMI. Ensure the PCB has a solid ground plane, and use a metal shield or a Faraday cage to enclose the converter.
  • Use a low-ESR ceramic capacitor with a value between 10uF to 22uF, and a voltage rating of at least 2x the input voltage. X5R or X7R dielectric types are recommended.
