Product Description
• Integrated filtering
The BCM4414xG0F4440yzz in a VIA package is a high efficiency
Bus Converter, operating from a 400 to 700VDC high voltage bus
to deliver an isolated 25 to 43.8VDC unregulated, low voltage.
• Parallel operation for multi-kW arrays
• OV, OC, UV, short circuit and thermal protection
• 4414 package
This unique ultra-low profile module incorporates DC-DC
conversion, integrated filtering and PMBus™ commands and
controls in a chassis or PCB mount form factor.
• High MTBF
• Thermally enhanced VIA package
• PMBus™ management interface
• Bidirectional operation (start up in forward direction only)
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.
• High Voltage DC Power Distribution
• 3 Phase AC-DC Converters
• 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
