Design Considerations
Thermal Management
Though DCM High Power modules have exceptional efficiency, thermal management remains critical at full power. Use appropriate heat sinking and consider the thermal resistance from junction to case. Pay attention to input and output capacitor placement to minimize conducted noise and ensure stable operation at high power levels.
Layout Recommendations
For optimal performance in high-power applications, ensure adequate PCB copper for heat spreading and proper thermal via placement for vertical heat transfer. Minimize current loops to reduce EMI at high power levels. DCMs benefit from the low switching losses due to ZVS operation, which reduces thermal management challenges.
System Integration
DCM High Power modules excel in applications where you need a simple, efficient DC-DC conversion without regulation at high power levels. They are ideal for bus conversion applications where downstream converters handle regulation.
