LTM8045IY#PBF Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. The device should be placed near a thermal pad or heat sink to dissipate heat efficiently.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure the input voltage rises slowly (e.g., 10ms to 100ms) to prevent excessive current draw. For shutdown, use a controlled shutdown sequence to prevent voltage spikes.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF, depending on the input voltage and output current requirements.
  • Use a shielded inductor, keep the layout compact, and use a common-mode choke or ferrite bead to filter the output. Also, ensure the PCB has a solid ground plane and use a Faraday shield if necessary.
  • The maximum ambient temperature for reliable operation is 85°C, but it can be derated to 70°C for high-reliability applications or in high-temperature environments.
