AS1M-HF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces as short as possible and use a common mode choke to reduce EMI.
  • Use a heat sink with a thermal resistance of less than 10°C/W and ensure good airflow around the device. Also, derate the output current according to the temperature derating curve in the datasheet.
  • The maximum allowed voltage spike is 1.5 times the maximum input voltage rating (Vin(max)) for a duration of less than 100ms. Exceeding this may damage the device.
  • Yes, but it's not recommended as it may lead to current imbalance and reduced reliability. If necessary, use a current sharing scheme with a dedicated controller and sense resistors.
  • Check the input voltage, output voltage, and output current. Verify that the input and output capacitors are properly connected and meet the recommended specifications. Also, check for any signs of overheating or physical damage.
