Cosel recommends a PCB layout with a large copper area for heat dissipation, and a minimum of 2oz copper thickness. A thermal via array under the module can also improve heat transfer.
To ensure reliable start-up and shutdown, Cosel recommends a soft-start circuit to limit inrush current, and a shutdown circuit with a voltage supervisor to prevent voltage drops.
Cosel provides derating curves in the datasheet, but for specific high-temperature applications, engineers can contact Cosel's technical support for customized derating curves.
Yes, the SUCS32405C can be used in redundant or N+1 configurations. However, engineers should ensure proper synchronization and control of the modules to prevent unwanted interactions.
Cosel recommends using a CISPR 22 Class B compliant EMI filter with a minimum attenuation of 30dB at 150kHz to ensure electromagnetic compatibility.
