Vicor Corporation has long been the pioneer in the design, development, manufacture, and marketing of modular power components and complete power systems used by OEMs in communications, computing, defense electronics, industrial control, medical, networking, and test equipment markets. The company's Intermediate Bus Converter (IBC) Module is a very efficient, low profile, isolated, fixed ratio converter for power system applications in enterprise and optical access networks. The IBC conforms to an industry standard eighth brick footprint while supplying the power of a quarter brick. Its leading efficiency enables full load operation at 55°C with only 200LFM airflow, a great advantage in tightly-packed telecom applications where density, efficiency and cooling are premium. Its small cross section facilitates unimpeded airflow - above and below its thin body - to minimize the temperature rise of downstream components. Vicor has now announced the introduction of the IBC048 series of VI BRICK™ Intermediate Bus Converters, which offer double the power density and half the conversion loss of competitive devices. Available as drop-in replacements for industry standard eighth-brick and quarter-brick 5:1 and 4:1 intermediate bus converters, initial product offerings include 300W and 500W models, providing 9.6V or 12V outputs from a nominal 48V input with a voltage range extending from 38V to 55V. IBC048-series modules provide pin-compatible upgrades for eighth-brick and quarter-brick bus converters and utilize Vicor's proprietary Sine Amplitude Converter™ engine which is fundamentally different from, and technologically superior to other competing technologies. The new VI BRICK Bus Converters utilize the same ZCS/ZVS engine that has powered V.I Chips™ into high performance applications with tier-one customers. Switching at approximately 10 times the frequency of competing bus converters, IBC048 modules cut transient response time from 200 to 20 microseconds, eliminating the need for bulk capacitors. Superior 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. "From pioneering the ‘brick' paradigm in the 1980s, Vicor has invested a substantial portion of its revenues in the R&D necessary to architect game-changing innovation in power electronics," said Robert Marchetti, Senior Manager of Product Marketing for Vicor's Brick Business Unit. "With this new product line, we are re-packaging remarkable advances achieved with V.I Chips and applying this superior technology to an established market that is now suffering from industry-wide shortages while still relying on traditional brick form factors." Samples of IBC048-series bus converters are available with 2 weeks lead time. Pricing starts at $39 in OEM quantities with 12 weeks lead time.
