LTM4668AIY#PBF 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 a heat sink with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Also, derate the output current according to the temperature derating curve in the datasheet.
  • The maximum capacitance is limited by the device's stability requirements. A maximum of 47µF is recommended, but it's essential to check the device's stability with the chosen capacitor value using the datasheet's stability analysis guidelines.
  • Yes, but it's crucial to ensure that the devices are synchronized and share the same input voltage and output voltage settings. Also, consider the increased power dissipation and thermal management requirements.
  • Check the PG signal's voltage level and ensure it's within the specified range. Verify that the input voltage is within the recommended range and that the output voltage is within the specified regulation range. Also, check for any short circuits or overcurrent conditions.
