CMC-05 - RECOM Power

CMC-05 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  RECOM recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure good heat dissipation.
• How do I ensure reliable start-up of the converter in cold temperatures?
  To ensure reliable start-up in cold temperatures, RECOM recommends adding a soft-start circuit or a voltage supervisor to prevent the converter from starting up in an unstable state.
• What is the maximum allowed capacitance on the output?
  The maximum allowed capacitance on the output is 47uF. Exceeding this value may cause instability or oscillation in the converter.
• Can I use the CMC-05 in a high-altitude application?
  Yes, the CMC-05 is suitable for high-altitude applications up to 20,000 feet. However, the derating curves should be consulted to ensure the converter operates within its specifications.
• How do I troubleshoot the converter if it's not functioning properly?
  RECOM recommends checking the input voltage, output voltage, and current draw to identify the root cause of the issue. A detailed troubleshooting guide is available in the application note.
