QSB35024S28 - XP POWER

QSB35024S28 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 connected to a heat sink or a metal plate for further heat dissipation.
• How do I ensure reliable start-up of the module in high-temperature environments?
  To ensure reliable start-up in high-temperature environments, XP Power recommends using a soft-start circuit or a ramp-up circuit to limit the inrush current during start-up. This helps to prevent the module from shutting down due to excessive current draw.
• What is the maximum capacitance I can use on the output of the module?
  The maximum capacitance on the output of the QSB35024S28 is 2200uF. Exceeding this value may cause the module to oscillate or become unstable. It's recommended to use a capacitance value that is within the specified range to ensure stable operation.
• Can I use the QSB35024S28 in a redundant configuration?
  Yes, the QSB35024S28 can be used in a redundant configuration to achieve high availability and reliability. However, it's essential to ensure that the modules are properly synchronized and that the output voltages are matched to prevent any potential issues.
• What is the recommended input fuse rating for the module?
  XP Power recommends using a fuse with a rating of 5A to 10A, depending on the input voltage and the maximum current rating of the module. The fuse should be able to handle the maximum inrush current during start-up and provide protection against overcurrent conditions.
