Product Description
The BCM4414xG0F4440yzz in a VIA package is a high efficiency
Bus Converter, operating from a 400 to 700V
DC
high voltage bus
to deliver an isolated 25 to 43.8V
DC
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.
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.
Leveraging the thermal and density benefits of Vicor’s VIA
packaging technology, the BCM module offers flexible thermal
management options with very low top and bottom side
thermal impedances.
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.
