LTM4681IY#PBF 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 and ensure good thermal conduction to the heat sink.
  • Use the provided filter design equations in the datasheet and optimize the component values for the specific application. Consider using a combination of ceramic and electrolytic capacitors for optimal performance.
  • The maximum allowed input voltage is 5.5V, but it's recommended to operate within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
  • Ensure a monotonic power-up and power-down sequence, and add a soft-start circuit to limit the inrush current. Also, add a capacitor to the EN pin to filter out noise and ensure reliable start-up.
  • Use a common-mode choke and a differential-mode filter capacitor to reduce EMI emissions. Follow the recommended layout guidelines and use a shielded inductor to minimize radiation.
