New BCM Bus Converter Modules with Unprecedented Performance

October 20, 2015

New 6123 ChiP-based DC-DC converters provide up to 98% efficiency and power density up to 2,870 W/in3

48 V BCMsToday we announced new members of our Bus Converter Module (BCM®) series of isolated, fixed conversion ratio, DC-DC converters. The new converters, which combine Vicor’s sine-amplitude DC-DC conversion technology with Vicor’s unique thermally adept Converter housed in Package (ChiP) packaging technology, outperform best-in-class contemporary products with:

  • More than five times the output power capability (up to 1,950 W)
  • 25% lower heat loss (typical efficiency of 98%)
  • Over four times the power density (up to 2,870 W/in3)

Designed for use in nominal 48 Volt power systems, these new converters operate over an input voltage range of 36 to 60 Volts 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 Watts 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 Watts of power.

Available in a 6123 (61 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 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 Volt power systems – as used, for example, in Telecom and Datacom datacenters and Power over Ethernet (PoE) applications – with unprecedented levels of density and efficiency.
