Product Description
The VI Chip® Bus Converter (BCM®) is a high efficiency
Sine Amplitude Converter™ (SAC™), operating from a 260 to
410 VDC primary bus to deliver an isolated, ratiometric output
from 32.5 to 51.3 VDC.
The BCM380x475y1K2A3z 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 BCM module. With a primary to
secondary K factor of 1/8, that capacitance value can be
reduced by a factor of 64x, resulting in savings of board area,
material and total system cost.
Leveraging the thermal and density benefits of Vicor’s ChiP
packaging technology, the BCM 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.
This product can operate in reverse direction, at full rated
power, after being previously started in forward direction.
