QSB40048S28 - XP POWER

QSB40048S28 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  XP Power recommends a PCB layout with a large copper area connected to the module's thermal pad to dissipate heat efficiently. A minimum of 2 oz copper thickness is recommended, and the copper area should be at least 1 inch x 1 inch in size.
• Can I use this module in a high-vibration environment?
  Yes, the QSB40048S28 is designed to withstand high-vibration environments. It meets the IEC 60068-2-6 vibration test standard, which simulates vibrations up to 10 G peak acceleration.
• How do I ensure the module's electromagnetic compatibility (EMC) in my system?
  To ensure EMC, XP Power recommends following the module's layout and grounding guidelines, using a metal enclosure, and adding EMI filters or shielding if necessary. Additionally, the module should be installed at least 1 inch away from other components to minimize electromagnetic interference.
• What is the maximum allowable capacitance for the output filter?
  The maximum allowable capacitance for the output filter is 47 μF. Exceeding this value may affect the module's stability and performance.
• Can I use this module in a redundant configuration?
  Yes, the QSB40048S28 can be used in a redundant configuration to achieve high reliability and availability. However, XP Power recommends consulting with their application engineers to ensure proper implementation and to discuss specific requirements.
