Product Description
Integrated filtering
The BCM4414xG0F4440yzz in a VIA package is a high-efcfi iency
Parallel operation for multi-kW arrays
Bus Converter, operating from a 400 to 700V high-voltage bus
DC
OV, OC, UV, short circuit and thermal protection
to deliver an isolated 25 to 43.8V unregulated, low voltage.
DC
4414 package
This unique ultra-low-prolfi e module incorporates DC-DC
conversion, integrated filtering and PMBus commands and
High MTBF
controls in a chassis or PCB mount form factor.
Thermally enhanced VIA package
The BCM offers low noise, fast transient response and
PMBus management interface
industry-leading efficiency and power density. A low-voltage-side
referenced PMBus-compatible telemetry and control interface
provides access to the BCMs congufi ration, fault monitoring and

other telemetry functions.
High-Voltage DC Power Distribution
Leveraging the thermal and density benefits of Vicor VIA packaging
technology, the BCM module offers flexible thermal management
3-Phase AC-DC Converters
options with very low top and bottom side thermal impedances.
Information and Communication
When combined with downstream Vicor DC-DC conversion
