BCM® Low-Voltage Bus Converter Modules for 48V

Vicor offers 48 V to 12 V, isolated, fixed-ratio bus converter modules

Image of Vicor's BCM® Low Voltage Bus Converter ModuleVicor's BCM low voltage bus converter modules are a series of isolated, fixed conversion ratio, DC-DC converters. These converters, which combine Vicor’s sine amplitude DC-DC conversion technology with Vicor’s unique thermally adept converter house in package (ChiP) packaging technology, feature more than five times the output power capability, 25% lower heat loss, and over four times the power density of best-in-class contemporary products.

Designed for use in nominal 48 V power systems, these converters operate over an input voltage range of 36 V to 60 V and are available in two conversion factors: a K=1/4 unit with output voltage that is one-fourth of its input voltage and delivers up to 1,950 W of power; and a K=1/6 unit with output voltage that is one-sixth of its input voltage and delivers up to 1,500 W of power. Available in a 6123 (61 mm x 23 mm) ChiP through-hole package, the units feature a typical 98% operating efficiency and market-leading power density of up to 2,870 W/in3. Configuration options include analog or PMBus[a] control interfaces and commercial or military temperature operating ranges.

Requiring less board area and fewer thermal management and output filter components than other solutions, these new BCMs, when combined with downstream regulators, enable customers to configure low cost 48 V power systems, as used, for example, in Telecom and Datacom datacenters and Power over Ethernet (PoE) applications, with unprecedented levels of density and efficiency.
