LDK120M31R 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 tracks as short as possible and use a common mode choke to reduce EMI.
  • Mount the device on a heat sink with a thermal conductivity of at least 1 W/m-K. Ensure good thermal contact between the device and heat sink using a thermal interface material. Keep the ambient temperature below 85°C.
  • The maximum allowed voltage on the input pins is 6.5V. Exceeding this voltage may damage the device.
  • Use a fuse or a current limiting resistor in series with the input to limit the current to 1.5A. You can also use a dedicated overcurrent protection IC.
  • The LDK120M31R is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. Consider using a heat sink and ensuring good airflow to keep the device within its operating temperature range.
