PSK-15D-15 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 2 oz copper thickness is recommended. Additionally, a thermal pad on the bottom of the device should be connected to a heat sink or a thermal management system.
• How do I ensure reliable operation in high-vibration environments?
  To ensure reliable operation in high-vibration environments, CUI recommends securing the device using a screw or adhesive, and using a conformal coating to protect the device from moisture and contaminants. Additionally, the PCB should be designed to minimize flexure and vibration transmission.
• What is the maximum allowable capacitance for the output filter capacitor?
  The maximum allowable capacitance for the output filter capacitor is 100 μF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use a different input voltage range than what is specified in the datasheet?
  No, the input voltage range is specified in the datasheet and should not be exceeded. Operating the device outside of the specified input voltage range may cause damage or affect the reliability of the device.
• How do I troubleshoot common issues such as output voltage droop or oscillation?
  To troubleshoot common issues, check the input voltage, output load, and PCB layout. Ensure that the device is properly soldered and that the output filter capacitor is within the recommended range. Also, check for any signs of overheating or physical damage.
