Product Description
The BCM4414xD1E13A2yzz in a VIA package is a high efficiency
Bus Converter, operating from a 260 to 410V
DC
high voltage bus to
deliver an isolated 8.1 to 12.8V
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.

The absolute maximum rating listed above for the dielectric withstand (high voltage side to the low voltage side) refers to the VIA package. The internal
safety approved isolating component (ChiP) provides reinforced insulation (4242V) from the high voltage side to the low voltage side. However, the VIA
package itself can only be tested at a basic insulation value (2121V).
