Product Description
• Integrated filtering
The BCM4414xH0E5035yzz in a VIA package is a high-efficiency
Bus Converter, operating from a 500 to 800VDC high-voltage bus
to deliver an isolated 31.3 to 50.0VDC 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
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
• High-Voltage DC Power Distribution
• 3-Phase AC-DC Converters
Leveraging the thermal and density benefits of Vicor VIA packaging
technology, the BCM module offers flexible thermal management
options with very low top and bottom side thermal impedances.
• 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
