DC 3814 package High MTBF This unique ultra-low-profile module incorporates DC-DC conversion, integrated filtering and PMBus commands and controls Thermally enhanced VIA package in a chassis or PCB mount form factor. PMBus management interface The BCM offers low noise, fast transient response and industry leading efficiency and power density. A low-voltage -side Typical Applications referenced PMBus-compatible telemetry and control interface provides access to the BCMs configuration, fault monitoring and DC Power Distribution other telemetry functions. Information and Communication Leveraging the thermal and density benefits of Vicor VIA packaging Technology (ICT) Equipment technology, the BCM module offers flexible thermal management High-End Computing Systems options with very low top- and bottom-side thermal impedances. Automated Test Equipment When combined with downstream Vicor DC-DC conversion Industrial Systems components and regulators, the BCM allows the Power Design High-Density Energy Systems Engineer to employ a simple, low-profile design, which will differentiate the end system without compromising on cost or Transportation performance metrics.
