Product Description
• Integrated ceramic capacitance filtering
• Parallel operation for multi-kW arrays
• OV, OC, UV, short circuit and thermal protection
• 3814 package
The BCM3814x60E15A3yzz in a VIA package is a high-efficiency
Bus Converter, operating from a 36 to 60VDC high-voltage bus to
deliver an isolated 9 to 15VDC 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
• DC Power Distribution
• Information and Communication
Technology (ICT) Equipment
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.
• High-End Computing Systems
• Automated Test Equipment
• Industrial Systems
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-Density Energy Systems
• Transportation
