Product Description
• Built-in EMI filtering and inrush limiting circuit
• Parallel operation for multi-kW arrays
• OV, OC, UV, short circuit and thermal protection
• 4414 package
The BCM4414xD1E5135yzz in a VIA package is a high efficiency
Bus Converter, operating from a 260 to 410VDC high voltage bus to
deliver an isolated 32.5 to 51.3VDC unregulated, low voltage.
This unique ultra-low profile module incorporates DC-DC
conversion, integrated filtering and PMBus™ [1] commands and
controls in a chassis or PCB mount form factor.
• High MTBF
• Thermally-enhanced VIA package
• PMBus™ management interface
• Suitable for Hot-Swap applications
The BCM offers low noise, fast transient response and industry
leading efficiency and power density. A low voltage side referenced
PMBus™ compatible telemetry and control interface provides
access to the BCM’s configuration, fault monitoring and other
telemetry functions.
Typical Applications
Leveraging the thermal and density benefits of Vicor’s VIA
packaging technology, the BCM module offers flexible thermal
management options with very low top and bottom side
thermal impedances.
• 380VDC Power Distribution
• Information and Communication
Technology (ICT) Equipment
When combined with downstream Vicor DC-DC conversion
components and regulators, the BCM allows the Power Design
Engineer to employ a simple, low-profile design, which will
differentiate the end system without compromising on cost or
performance metrics.
• High-End Computing Systems
• Automated Test Equipment
• Industrial Systems
• High Density Energy Systems
• Transportation
• Green Buildings and Microgrids
