LTM4650AEY-1#PBF Frequently Asked Questions (FAQs)

  • A 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 prevent latch-up. For shutdown, ensure the input voltage falls slowly to prevent voltage spikes.
  • A low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10-22uF is recommended to filter the input voltage and reduce noise.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive nodes, and use a common-mode choke to reduce EMI. Also, ensure the PCB layout is compact and symmetrical to reduce radiation.
  • The maximum allowed output capacitance is 100uF. Exceeding this value may cause instability or oscillations in the output voltage.
