LTM4651IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pad connected to the ground plane to improve heat dissipation.
  • Use a combination of ceramic and electrolytic capacitors for the output filter. Choose capacitors with low ESR and high ripple current ratings. Optimize the inductor value and type for the specific application.
  • The maximum allowed input voltage transient is 20% above the maximum recommended input voltage (Vin_max) for a duration of 100ms. Exceeding this may cause damage to the device.
  • Use a soft-start circuit to limit the inrush current during start-up. Ensure the input voltage rises slowly (typically 10ms to 100ms) to prevent excessive inrush current. For shutdown, ensure the input voltage falls slowly 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 current requirements.
