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 32.5 to 51.3 VDC
unregulated secondary voltage.

Typical Applications
The BCM380y475x1K2A30 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 input of the BCM module. With a 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.

• Transportation
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.
