Vicor introduces advanced ChiP packaging for enhanced power density and thermal performance. The new technology enables 50% higher power density compared to previous generations, addressing the growing demand for more compact power solutions in data centers, AI systems, and other high-performance applications.
Introduction to Advanced ChiP Technology
The power electronics industry is facing unprecedented demand for higher power density as applications become more compact while requiring more processing power. From data centers supporting AI workloads to electric vehicles requiring efficient power conversion, the industry needs solutions that deliver more power in less space without compromising efficiency or reliability.
Vicor's new ChiP (Converter housed in Package) technology represents a significant advancement in this area, housing the entire power converter within a surface-mount package with all components fully integrated. This eliminates the need for external magnetics, capacitors, and other passive components traditionally required in power designs.
Technical Innovations in the New ChiP Design
The new ChiP packaging incorporates several key innovations that contribute to the 50% improvement in power density:
- Advanced Component Integration: Next-generation component integration techniques allow for more power processing capability in the same footprint.
- Enhanced Thermal Pathways: Improved thermal design with optimized heat transfer paths from active components directly to the package surface.
- Miniaturized Magnetics: Revolutionary magnetic design techniques that reduce the physical size of inductors and transformers while maintaining performance.
- High-Density Capacitor Integration: Advanced capacitor integration technology that replaces multiple discrete capacitors with integrated solutions.
Applications Benefiting from Enhanced Power Density
The improved power density of the new ChiP technology enables several applications:
Data Centers and High-Performance Computing
Data center applications, particularly those supporting AI and machine learning workloads, benefit significantly from the enhanced power density. The ability to deliver more power per unit area allows for higher server density without increasing the physical footprint or thermal dissipation requirements.
Electric Vehicle Power Systems
Electric vehicles require compact, efficient power conversion systems to maximize range and minimize weight. The new ChiP technology enables battery management systems, on-board chargers, and DC-DC converters with smaller form factors and improved efficiency.
Industrial and Transportation Systems
Industrial automation and transportation applications often have severe space constraints while requiring high reliability. The new ChiP technology provides these benefits without compromising on performance or safety requirements.
Performance Comparison with Previous Generations
Testing of the new ChiP packaging technology demonstrates significant improvements compared to previous generations:
- Power Density: 50% increase in watts per cubic centimeter
- Thermal Performance: 15% improvement in thermal resistance (θJA)
- Efficiency: Maintained or improved efficiency across the full load range
- EMI Performance: Better EMI characteristics due to superior component integration
Implementation Considerations
While the new ChiP technology provides significant benefits, implementation requires attention to several considerations:
PCB Design Requirements
The enhanced thermal performance of the new ChiP packages still requires proper PCB thermal design to ensure optimal heat transfer. This includes:
- Adequate copper area for heat spreading
- Thermal vias for vertical heat transfer
- Proper pad design for thermal and mechanical connection
- Board material selection for thermal performance
Manufacturing Considerations
The new ChiP packages are designed to be compatible with standard SMT manufacturing processes, but specific guidelines should be followed for optimal results:
- Reflow profile optimization for thermal performance
- Handling and storage requirements
- Inspection and testing procedures
- Reliability validation processes
