DC 2.494 x 0.898 x 0.284in The BCM6123xD1E5126yzz offers low noise, fast transient 63.34 x 22.80 x 7.21mm response, and industry leading efficiency and power density. In a PMBus management interface 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 Typical Applications side of the BCM. With a primary to secondary K factor of 1/8, that capacitance value can be reduced by a factor of 64x, resulting in 380V Power Distribution DC savings of board area, material and total system cost. High-End Computing Systems Leveraging the thermal and density benefits of Vicor ChiP Automated Test Equipment packaging technology, the BCM offers flexible thermal management options with very low top and bottom side thermal Industrial Systems impedances. Thermally-adept ChiP-based power components High-Density Power Supplies enable customers to achieve low cost power system solutions with previously unattainable system size, weight and efficiency Communications Systems attributes quickly and predictably. Transportation This product can operate in the reverse direction, at full rated current, after being previously started in the forward direction. a When used with D44TL1A0 and I13TL1A0 BCM Bus Converter Rev 1.4 Page 1 of 30 07/2018BCM6123xD1E5126yzz Typical Applications BCM TM EN enable/disable switch VAUX F1 +V +V PRI SEC V C PRI PoL PRI V V PRI SEC GND PRIMARY SECONDARY ISOLATION BOUNDARY BCM6123xD1E5126y00 at point-of-load BCM SER-OUT SER-OUT EN SER-IN enable/disable switch SER-IN FUSE +V +V PRI SEC V C PoL PRI I BCM ELEC V V PRI SEC PRIMARY SECONDARY SOURCE RTN Digital ISOLATION BOUNDARY Supervisor Digital Isolator D44TL1A0 Host C I13TL1A0 NC PRI OUT A SEC IN A VDDB t SER-IN + V EXT VDD PRI OUT B SEC IN B TXD SER-OUT SGND PRI IN C SEC OUT C RXD PRI COM SEC COM SGND PMBus PMBus SGND SGND SGND BCM6123xD1E5126y01 at point-of-load BCM Bus Converter Rev 1.4 Page 2 of 30 07/2018 SW1
