PDS2-S24-S12-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 large copper area for heat dissipation, and thermal vias to connect to a heat sink or a metal core PCB. A minimum of 2oz copper thickness is recommended. Additionally, ensure good airflow around the device to prevent overheating.
• How do I ensure the DC-DC converter's output voltage is stable and regulated?
  To ensure stable output voltage, make sure to add the recommended output capacitors (e.g., 10uF ceramic and 22uF electrolytic) and follow the datasheet's guidance on output voltage setting resistors. Also, ensure the input voltage is within the specified range and the device is operated within its recommended temperature range.
• What is the maximum allowable ripple current on the input capacitors?
  The maximum allowable ripple current on the input capacitors is typically 20-30% of the device's input current rating. For the PDS2-S24-S12-M-TR, this would be around 1-1.5A. However, it's recommended to consult the capacitor manufacturer's datasheet for specific ripple current ratings.
• Can I use this DC-DC converter in a high-vibration or high-shock environment?
  While the PDS2-S24-S12-M-TR is designed to be rugged, it's essential to ensure the device is properly secured to the PCB and the PCB is securely fastened to the system. Additionally, consider using vibration-resistant components and follow good design practices for high-vibration or high-shock environments.
• How do I troubleshoot issues with the DC-DC converter, such as no output voltage or overheating?
  Start by verifying the input voltage and current, and ensure the device is properly connected and configured. Check the output voltage and current, and verify the output capacitors are properly sized and connected. If issues persist, consult the datasheet's troubleshooting section or contact CUI's technical support for assistance.
