PDQ15-Q48-S15-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 to ensure stable operation and minimize EMI.
• Can I use this DC-DC converter in a high-temperature environment?
  While the PDQ15-Q48-S15-D is rated for operation up to 85°C, it's essential to consider derating the output power and ensuring proper airflow to prevent overheating. Consult with CUI Inc or a thermal expert for specific guidance.
• How do I ensure electromagnetic compatibility (EMC) in my system?
  To ensure EMC, follow proper PCB layout and grounding practices, use shielding if necessary, and consider adding EMI filters or common-mode chokes to the input and output lines. CUI Inc also recommends following relevant industry standards (e.g., EN 55022, CISPR 22).
• What is the maximum allowable input voltage ripple?
  While the datasheet doesn't specify a maximum input voltage ripple, a general rule of thumb is to keep the input voltage ripple below 10% of the nominal input voltage to ensure stable operation and prevent damage to the converter.
• Can I parallel multiple PDQ15-Q48-S15-D converters for higher output power?
  Yes, you can parallel multiple converters, but it's crucial to ensure that the output voltages are matched and the converters are synchronized to prevent oscillations. Consult with CUI Inc or a power electronics expert for specific guidance on paralleling these converters.
