PS2805C-1-A 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 short and away from each other to minimize noise and EMI.
  • Use a thermal pad or thermal interface material to improve heat dissipation. Ensure good airflow and avoid blocking airflow around the device. Follow the recommended operating conditions and derating guidelines.
  • Use a pi-filter (C-L-C) or a common-mode choke on the input and output lines to reduce EMI. Add a TVS diode or a zener diode for overvoltage protection. Ensure the filter components are rated for the maximum input voltage.
  • Choose an input capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A ceramic capacitor (X7R or X5R) with a voltage rating of 1.5 to 2 times the maximum input voltage is recommended.
  • Use a heat sink with a thermal resistance of 10°C/W or lower. Apply a thermal interface material to the heat sink and device. Ensure good airflow and avoid blocking airflow around the heat sink.
