Product Description
The NBM6123x60E12A7yzz Non-Isolated Bus Converter (NBM™)
is a high efficiency Sine Amplitude Converter™ (SAC™), operating
from a 36 to 60V_DC primary bus to deliver a non-isolated,
ratiometric secondary voltage from 7.2 to 12.0V_DC.
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
ackaging 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.
