Product Description
• Built-in EMI filtering and inrush limiting circuit
• Parallel operation for multi-kW arrays
• OV, OC, UV, short circuit and thermal protection
• 4414 package
The BCM4414xD1E13A3yzz in a VIA package is a high efficiency
Bus Converter, operating from a 260 to 410VDC high-voltage bus to
deliver an isolated 8.1 to 12.8VDC 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
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.
• Thermally enhanced VIA package
• PMBus® management interface
• Suitable for Hot-Swap 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.
Typical Applications
• 380VDC Power Distribution
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.
