PRQ100W-Q48-S5-D Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and thermal management for optimal performance?
  CUI Inc recommends a PCB layout with a large copper area for heat dissipation, and a thermal management system with a heat sink and thermal interface material to keep the device temperature below 100°C.
• How do I ensure reliable startup and shutdown of the converter?
  To ensure reliable startup and shutdown, CUI Inc recommends a soft-start circuit to limit inrush current, and a shutdown circuit to discharge the output capacitors. Additionally, a voltage supervisor can be used to monitor the input voltage and prevent startup during brownout conditions.
• What is the maximum allowable capacitance on the output of the converter?
  The maximum allowable capacitance on the output of the PRQ100W-Q48-S5-D is 2200uF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use this converter in a redundant or parallel configuration?
  Yes, the PRQ100W-Q48-S5-D can be used in a redundant or parallel configuration, but it requires additional circuitry to ensure proper operation and fault tolerance. CUI Inc recommends consulting with their application engineers for guidance on implementing such a configuration.
• What is the expected lifespan and reliability of the converter?
  The PRQ100W-Q48-S5-D has a predicted lifespan of 10-15 years, with a failure rate of less than 1% per 1000 hours. However, this can vary depending on the operating conditions, quality of the components, and manufacturing process.
