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
8.13 to 12.81 VDC.

• PMBusTM management interface*
The BCM384y120x800AC1 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 1/32, that
capacitance value can be reduced by a factor of 1024x, resulting
in savings of board area, material and total system cost.
Typical Applications
• 380 DC Power Distribution
• High End Computing Systems
• Automated Test Equipment
• Industrial Systems
The BCM384y120x800AC1, 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.
• High Density Power Supplies
• Communications Systems
• 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.
