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 CMC-08 can drive a maximum capacitive load of 10uF. Exceeding this value may cause instability or oscillations.
While the CMC-08 is rated for operation up to 85°C, RECOM recommends derating the output power by 1.5% per degree above 70°C to ensure reliable operation.
To troubleshoot output voltage deviations or oscillations, check the input voltage, output load, and PCB layout for any anomalies or noise sources. Ensure that the input and output capacitors are of sufficient value and type.
