PDS1-S5-S15-M-TR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI recommends a PCB layout with a solid ground plane and thermal vias to dissipate heat. A minimum of 1 oz copper thickness is recommended. For thermal management, ensure good airflow and consider adding a heat sink if the device will be operating at high temperatures or high currents.
• How do I ensure electromagnetic compatibility (EMC) with this DC-DC converter?
  To ensure EMC, follow proper PCB layout and grounding techniques, use a metal enclosure, and consider adding EMI filters or shielding to the design. Additionally, ensure the converter is operated within its specified frequency range and follow CUI's recommended layout guidelines.
• What is the derating curve for this converter, and how does it affect performance?
  The derating curve for the PDS1-S5-S15-M-TR is available upon request from CUI. The curve shows the maximum recommended output current at various ambient temperatures. Operating the converter above the derated current can reduce its lifespan and affect performance.
• Can I use this converter in a redundant or parallel configuration?
  Yes, the PDS1-S5-S15-M-TR can be used in redundant or parallel configurations, but it's essential to follow CUI's guidelines for synchronization and current sharing to ensure reliable operation and prevent damage to the converters.
• What are the recommended input and output capacitors for this converter?
  CUI recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the input voltage. For the output, use capacitors with a voltage rating of at least 1.5 times the output voltage. The recommended capacitance values can be found in the datasheet or by contacting CUI's technical support.
