Product Description
The BCM3814x60E15A3yzz in a VIA package is a high efficiency
Bus Converter, operating from a 36 to 60V
DC
high voltage bus to
deliver an isolated 9 to 15V
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.
