LTM4678IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads connected to the ground plane to improve heat dissipation.
  • Use the provided filter design tool or consult the application note AN136 to determine the optimal output filter component values for your specific application.
  • The maximum capacitive load is 10nF. Exceeding this value may cause instability or oscillations.
  • Use a soft-start circuit to limit the inrush current during start-up, and ensure that the input voltage rises monotonically during power-up. For shutdown, ensure that the input voltage falls below the undervoltage lockout threshold.
  • Use a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the input voltage and current requirements.
