MGFS62415 - Cosel

MGFS62415 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Cosel recommends a multi-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) should be used between the module and the heat sink to ensure efficient heat transfer.
• How do I ensure reliable start-up and shutdown of the power supply?
  To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit inrush current and a power-good signal to monitor the output voltage. Additionally, a delay circuit can be used to stagger the start-up of multiple modules.
• What are the derating curves for temperature and altitude?
  Cosel provides derating curves for temperature and altitude in the application notes section of the datasheet. The curves provide guidance on reducing the output power to ensure reliable operation under extreme environmental conditions.
• Can I use the MGFS62415 in a redundant or N+1 configuration?
  Yes, the MGFS62415 can be used in a redundant or N+1 configuration. Cosel recommends using a diode ORing circuit to connect multiple modules in parallel, and a redundancy controller to monitor and control the modules.
• What is the MTBF and FIT rate of the MGFS62415?
  The MTBF (Mean Time Between Failures) and FIT (Failures In Time) rates of the MGFS62415 are calculated based on the Telcordia SR-332 Issue 4 standard. The MTBF is approximately 1.4 million hours, and the FIT rate is approximately 700 FITs per billion hours.
