PYBJ3-D24-S5-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  CUI recommends a PCB layout with a large copper area connected to the tab of the device to dissipate heat efficiently. A minimum of 1 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use this DC-DC converter in a high-vibration environment?
  Yes, the PYBJ3-D24-S5-D is designed to withstand high-vibration environments. It meets the IEC 60068-2-6 vibration test standard, which ensures reliable operation in applications with vibration levels up to 10G.
• How do I ensure electromagnetic compatibility (EMC) with this converter?
  To ensure EMC, CUI recommends following proper PCB layout and design guidelines, such as keeping the input and output traces separate, using a common-mode choke, and adding EMI filters as needed. Additionally, the converter meets the CISPR 22 Class B and FCC Part 15 Class B EMC standards.
• What is the maximum capacitance I can use on the output?
  The maximum output capacitance recommended by CUI is 2200uF. Exceeding this value may affect the stability of the converter and lead to oscillations or reduced performance.
• Can I parallel multiple PYBJ3-D24-S5-D converters for higher power?
  Yes, you can parallel multiple converters to achieve higher power output. However, CUI recommends consulting their application notes and following proper design guidelines to ensure reliable operation and avoid any potential issues.
