MGXW62412 - Cosel

MGXW62412 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  Cosel recommends a PCB layout with a solid ground plane and a thermal pad connected to the ground plane to dissipate heat. A minimum of 2oz copper thickness is recommended. Additionally, a thermal interface material (TIM) with a thermal conductivity of 1W/m-K or higher is suggested between the module and the heat sink.
• How do I ensure reliable start-up and shutdown of the module?
  To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit the inrush current and a shutdown circuit to discharge the output capacitors. The recommended soft-start time is 10-20ms, and the shutdown time should be longer than the soft-start time.
• What are the derating curves for the module's output power and efficiency at high temperatures?
  Cosel provides derating curves for output power and efficiency at high temperatures in the application notes or upon request. Typically, the output power derates by 1-2% per degree Celsius above 50°C, and the efficiency derates by 0.5-1% per degree Celsius above 50°C.
• Can I use the MGXW62412 in a redundant or parallel configuration?
  Yes, the MGXW62412 can be used in a redundant or parallel configuration, but it requires careful design and consideration of the system's overall architecture. Cosel recommends consulting with their application engineers to ensure proper implementation and to discuss any specific requirements or limitations.
• What are the EMI filter requirements for the MGXW62412?
  Cosel recommends using a CISPR 22 Class B compliant EMI filter at the input of the module to ensure compliance with electromagnetic interference regulations. The filter should be designed to attenuate conducted emissions in the frequency range of 150kHz to 30MHz.
