PYBJ6-D24-S5-OD 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. Additionally, a thermal interface material (TIM) can be used to improve heat transfer between the module and the heat sink.
• How do I ensure reliable operation in high-vibration environments?
  CUI recommends following the recommended PCB mounting and screw torque specifications to ensure the module is securely fastened. Additionally, using a conformal coating and potting the module can help protect it from vibration and environmental factors.
• What is the derating curve for the module's output power versus ambient temperature?
  CUI provides a derating curve in the datasheet, but it's also available upon request. The curve shows the recommended output power reduction as a function of ambient temperature to ensure reliable operation.
• Can I use this module in a redundant or parallel configuration?
  Yes, the PYBJ6-D24-S5-OD 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 avoid damage to the modules.
• What is the module's behavior during input voltage brownout or dropout?
  The PYBJ6-D24-S5-OD has built-in undervoltage protection, which will shut down the module if the input voltage falls below a certain threshold (typically around 16V). The module will automatically restart when the input voltage returns to a safe operating level.
