Vicor Corp. has released quarter-brick modules in its IBC048 series of VI BRICK Bus Converters that are said to achieve 98 percent efficiency by delivering up to 650W at 9.6V or 12V from a nominal 48V within a 38V to 55V input range. Available as drop-in for 5:1 and 4:1 converters, the modules expand upon the capabilities of recently announced IBC048 eighth-brick modules with 300W and 500W power ratings.

The IBC048 series modules use Vicor's Sine Amplitude Converter topology. They are pin-compatible industry standard "square wave" bus converters and offer higher performance.


VI BRICK Bus Converter

The VI BRICK Bus Converters utilize the Vicor patented ZCS/ZVS resonant converter technology that powers V.I Chips in high performance Factorized Power Architecture applications. Switching at approximately 10 times the frequency of square wave converters, IBC048 modules cut transient response time by a factor of 10, eliminating the need for external bulk capacitors. Superior power density and conversion efficiency enable competitive advantages for OEMs seeking to maximize performance across a range of applications, including computing, data storage, networking and Power-over-Ethernet.

The IBC048 modules are priced at less than $0.12 per watt in OEM quantities. Samples of IBC048 series bus converters are available from stock.
