ROM-1205S Frequently Asked Questions (FAQs)

  • 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.
  • 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.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillation in the converter.
  • Yes, the ROM-1205S 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.
  • 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.
