Product Description
The VI Chip® Non-Isolated Bus Converter (NBM™) is a high
efficiency Sine Amplitude Converter™ (SAC™), operating from
a 36 to 60 VDC primary bus to deliver a non-isolated,
ratiometric output from 7.2 to 12.0 VDC.
The NBM6123x60E12A7yzz offers low noise, fast transient
response, and industry leading efficiency and power density. In
addition, it provides an AC impedance beyond the bandwidth
of most downstream regulators, allowing input capacitance
normally located at the input of a POL regulator to be located at
the primary side of the NBM module. With a primary to
secondary K factor of 1/5, that capacitance value can be
reduced by a factor of 25x, resulting in savings of board area,
material and total system cost.
Leveraging the thermal and density benefits of Vicor’s ChiP
packaging technology, the NBM module offers flexible thermal
management options with very low top and bottom side
thermal impedances. Thermally-adept ChiP-based power
components, enable customers to achieve low cost power
system solutions with previously unattainable system size,
weight and efficiency attributes, quickly and predictably.
The NBM non-isolated topology allows operation in forward
and reverse directions and provides bidirectional protections.
However if power train is disabled by any protection, and V_SEC
is present, then voltage equal to V_SEC minus two diode drops
will appear on primary side.
