VICOR BCM380P475M800A31

The BCM6123xD1E5116yzz bus converter is a high-efficiency sine amplitude converter operating from a 260 to 410 VDC primary bus, delivering 32.5 to 51.3 VDC isolated, ratio-metric secondary voltage. The product features low noise, fast transient response, and industry-leading efficiency and power density. In addition, it presents an AC impedance that exceeds the bandwidth of most downstream regulators, enabling the input capacitance typically placed at the input of point-of-load regulators to be relocated to the primary side of the BCM module. With a 1/8 primary-to-secondary K factor, this capacitance value can be reduced by 64×, saving board area, bill of materials, and overall system cost. Leveraging the thermal performance and density advantages of ChiP packaging technology, the BCM module offers flexible thermal management options with very low top- and bottom-side thermal impedance. The thermally adaptable ChiP-based power component enables customers to rapidly and predictably realize low-cost power system solutions with system size, weight, and efficiency attributes previously unattainable. The product is capable of reverse full-rated-power operation following a prior forward startup.
