PDQ15-Q24-S15-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI recommends a PCB layout with a solid ground plane and thermal vias under the device to improve heat dissipation. A minimum of 2 oz copper thickness is recommended.
• Can I use this DC-DC converter in a high-vibration environment?
  Yes, the PDQ15-Q24-S15-D is designed to meet the requirements of IEC 60068-2-6 for vibration resistance. However, it's recommended to consult with CUI's application engineers for specific vibration profiles and mounting recommendations.
• How do I ensure electromagnetic compatibility (EMC) with this converter?
  CUI recommends following proper PCB layout and design guidelines, using a metal enclosure, and adding EMI filters as needed. Additionally, the PDQ15-Q24-S15-D has built-in EMI filtering, but it's still important to follow good EMC design practices.
• What is the maximum capacitance I can use on the output?
  CUI recommends a maximum output capacitance of 2200 μF to ensure stability and prevent oscillation. Exceeding this value may affect the converter's performance and reliability.
• Can I parallel multiple units for higher power output?
  Yes, the PDQ15-Q24-S15-D can be paralleled for higher power output, but it's essential to follow CUI's application notes and guidelines for paralleling DC-DC converters to ensure proper operation and reliability.
