Product Description
The BCM6123xD1E13A3yzz is a high-efficiency Bus Converter,
operating from a 260 to 410V
DC
primary bus to deliver an isolated,
ratiometric secondary voltage from 8.1 to 12.8V
DC
.
The BCM6123xD1E13A3yzz 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. With a primary to secondary 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.
Leveraging the thermal and density benefits of Vicor ChiP
packaging technology, the BCM 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 the reverse direction, at full rated
current, after being previously started in the forward direction.
