BCM Bus Converter MIL-COTS BCM6123xD0G5030yzz S CUNRTL S C US Isolated Fixed-Ratio DC-DC Converter Features & Benefits Product Ratings Up to 30A continuous secondary current V = 270V (200 400V) I = up to 30A PRI SEC 3 Up to 2342W/in power density V = 33.8V (25 50V) SEC 97.9% peak efficiency K = 1/8 (no load ) 4,242V isolation DC Product Description Parallel operation for multi-kW arrays OV, OC, UV, short circuit and thermal protection The BCM6123xD0G5030yzz is a high-efficiency Bus Converter, operating from a 200 to 400V primary bus to deliver an isolated, DC BCM6123 through-hole ChiP package ratiometric secondary voltage from 25 to 50V . DC 2.494 x 0.898 x 0.284in The BCM6123xD0G5030yzz 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 High-Voltage 270V Aircraft Distributed Power DC savings of board area, material and total system cost. 28 and 48V MIL-COTS PRM Interface DC Leveraging the thermal and density benefits of Vicor ChiP High-Density Mil Power Supplies packaging technology, the BCM offers flexible thermal management options with very low top and bottom side thermal Mil Communications Systems 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. a When used with D44TL1A0 and I13TL1A0 BCM Bus Converter Rev 1.3 Page 1 of 30 07/2018BCM6123xD0G5030yzz 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 BCM6123xD0G5030y00 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 BCM6123xD0G5030y01 at point-of-load BCM Bus Converter Rev 1.3 Page 2 of 30 07/2018 SW1
