LDK320AU50R Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
  • To ensure reliable operation at high temperatures, it is recommended to derate the device's power dissipation according to the temperature derating curve provided in the datasheet, and to ensure good thermal conduction to the heat sink or PCB.
  • STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10-22uF, X5R or X7R dielectric, and a voltage rating of 50V or higher, placed as close as possible to the device's input pins.
  • To prevent EMI issues, it is recommended to use a shielded layout, keep the device's input and output traces short and away from noise sources, and use a common-mode choke or ferrite bead on the input lines.
  • STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10-22uF, X5R or X7R dielectric, and a voltage rating of 50V or higher, placed as close as possible to the device's output pins.
