Product Description
The NBM in a VIA package is a high efficiency Bus Converter,
operating from a 36 to 60V_DC high voltage bus to deliver a non-
isolated 7.2 to 12V_DC unregulated, low voltage.
This unique ultra-low profile module incorporates DC-DC
conversion, integrated filtering in a chassis or PCB mount
form factor.
The NBM offers low noise, fast transient response and industry
leading efficiency and power density.
Leveraging the thermal and density benefits of Vicor’s VIA
packaging technology, the NBM 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 NBM 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 NBM non-isolated topology allows start up and steady state
operation in forward and reverse directions. It provides
bidirectional protections. However if power train is disabled by any
protection, and V_LO is present, then voltage equal to V_LO minus two
diode drops will appear on high voltage side.
