The BCM6123xD1E5126yzz Bus Converter (BCM®) is a high
efficiency Sine Amplitude Converter™ (SAC™), operating from
a 260 to 410VDC primary bus to deliver an isolated, ratiometric
■■2.494” x 0.898” x 0.286”
secondary voltage from 32.5 to 51.3VDC
.
(63.34mm x 22.80mm x 7.26mm)
The BCM6123xD1E5126yzz 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.
• PMBus™ management interface*
Typical Applications
• 380VDC Power Distribution
• High End Computing Systems
• Automated Test Equipment
• Industrial Systems
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.
• High Density Power Supplies
• Communications Systems
• Transportation
This product can operate in reverse direction, at full rated power,
after being previously started in forward direction.
