LTM4680IY Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal pads away from high-current paths and ensure good airflow around the device.
  • Use the provided filter design tool or consult the application note AN136 to determine the optimal output filter component values. Ensure the filter is placed close to the output pins and use a low-ESR capacitor.
  • The LTM4680IY can withstand input voltage transients up to 20% above the maximum rated input voltage for a duration of 100ms. However, it's recommended to use a TVS diode or a voltage clamp to protect the device from excessive voltage spikes.
  • 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, use a controlled shutdown sequence to prevent voltage spikes.
  • Use a low-ESR ceramic capacitor (X5R or X7R dielectric) with a value between 10uF to 22uF, depending on the input voltage and current requirements. Ensure the capacitor is placed close to the input pins.
