PDQ10-Q24-S3-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  CUI Inc recommends a PCB layout with a solid ground plane, minimal trace length, and a decoupling capacitor (e.g., 10uF) between the input and output pins to ensure stable operation and minimize EMI.
• Can I use this DC-DC converter in a high-temperature environment?
  While the PDQ10-Q24-S3-D is rated for operation up to 85°C, it's essential to consider derating the output power and ensuring adequate airflow to prevent overheating. Consult CUI Inc's application notes for guidance on high-temperature operation.
• How do I ensure electromagnetic compatibility (EMC) with this converter?
  To ensure EMC, follow proper PCB layout and grounding practices, use a metal shield or enclosure, and consider adding EMI filters or common-mode chokes to the input and output lines. CUI Inc provides EMC guidelines in their application notes.
• What is the maximum capacitive load I can connect to the output?
  The PDQ10-Q24-S3-D can handle a maximum capacitive load of 10uF. Exceeding this value may cause instability or oscillation. If you need to connect a larger capacitor, consider adding a series resistor or inductor to limit the inrush current.
• Can I parallel multiple converters to increase the output power?
  Yes, you can parallel multiple PDQ10-Q24-S3-D converters to increase the output power. However, ensure that each converter has its own input filter and decoupling capacitor, and that the outputs are connected in parallel with a common output capacitor. Consult CUI Inc's application notes for guidance on paralleling converters.
