Product Description
• Integrated ceramic capacitance filtering
• Parallel operation for multi-kW arrays
• OV, OC, UV, short circuit and thermal protection
• 3814 package
The BCM3814x60E10A5yzz in a VIA package is a high-efficiency
Bus Converter, operating from a 36 to 60VDC high-voltage bus to
deliver an isolated 6 to 10VDC unregulated, low voltage.
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
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.
• DC 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
