MD1803DFX Frequently Asked Questions (FAQ)

  • STMicroelectronics recommends a 2-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.

  • Implement a thermal management system, such as a heat sink or fan, to keep the junction temperature below 150°C. Also, ensure good airflow and avoid thermal hotspots.

  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling, placed as close to the device as possible.

  • Use a shielded enclosure, keep the layout compact, and use a common-mode choke or ferrite bead on the input lines to reduce EMI emissions.

  • The maximum allowed voltage drop is 0.5V, but it's recommended to keep it below 0.3V to ensure reliable operation.
