BCM Bus Converter BCM6123xD1E2663yzz S CUNRTL S C US Isolated Fixed-Ratio DC-DC Converter Features & Benefits Product Ratings Up to 62.5A continuous secondary current V = 384V (260 410V) I = up to 62.5A PRI SEC 3 Up to 2352W/in power density V = 24V (16.3 25.6V) SEC 97.4% peak efficiency K = 1/16 (no load ) 4,242V isolation DC Product Description Parallel operation for multi-kW arrays OV, OC, UV, short circuit and thermal protection The BCM6123xD1E2663yzz is a high-efficiency Bus Converter, operating from a 260 to 410V primary bus to deliver an isolated, a DC PMBus management interface ratiometric secondary voltage from 16.3 to 25.6V . DC The BCM6123xD1E2663yzz offers low noise, fast transient Typical Applications response, and industry leading efficiency and power density. In addition, it provides an AC impedance beyond the bandwidth of 380V Power Distribution DC most downstream regulators, allowing input capacitance normally High-End Computing Systems 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 1/16, that Automated Test Equipment capacitance value can be reduced by a factor of 256x, resulting in savings of board area, material and total system cost. Industrial Systems Leveraging the thermal and density benefits of Vicor ChiP High-Density Power Supplies packaging technology, the BCM offers flexible thermal Communications Systems management options with very low top and bottom side thermal impedances. Thermally-adept ChiP-based power components Transportation 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.
