PSK-4-3 Frequently Asked Questions (FAQs)

  • CUI recommends following a 4-layer PCB stackup with a solid ground plane on the bottom layer, a power plane on the inner layer, and signal traces on the outer layers. Keep the power traces as short and wide as possible, and use vias to connect the power planes to the component pads.
  • CUI recommends derating the output power by 1% per degree Celsius above 50°C. Ensure good airflow around the module, and consider using a heat sink or thermal interface material to improve thermal dissipation.
  • CUI recommends using a 10uF to 22uF input capacitor with a low ESR (Equivalent Series Resistance) to filter the input voltage and reduce ripple.
  • Yes, the PSK-4-3 can be used in a redundant configuration with another identical module. However, ensure that the output voltages are synchronized and the output capacitors are properly sized to handle the increased output current.
  • CUI recommends limiting the output capacitance to 100uF maximum to prevent excessive inrush current during startup.
