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 BCM400y500x1K8A31 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.
The BCM400y500x1K8A31, combined with the D44TL1A0
Digital Supervisor and I13TL1A0 Digital Isolator, provide a
secondary referenced PMBus™ compatible telemetry and
control interface. This interface provides access to the BCM’s
internal controller configuration, fault monitoring, and other
telemetry functions.
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.
