Artesyn 2nd Generation Intermediate Bus Converters Raise the Power Bar to 450 Watts FRAMINGHAM, Mass., June 27 /PRNewswire-FirstCall/ -- Artesyn Technologies Inc. (NASDAQ:ATSN) has launched a new series of ultra high efficiency Typhoon(TM) quarter-brick intermediate bus converters (IBCs) that generate up to 50% more useable power than previous generation models. The series includes an unregulated, fixed ratio DC transformer for computing, and two semi- regulated models optimized for telecom and networking applications. All three IBCs employ a new, leading edge conversion topology to maximize efficiency and power density. The unregulated model, for example, can deliver up to 450W of output power -- 150W more than its one-quarter brick predecessor -- with an efficiency of over 95%. (Logo: http://www.newscom.com/cgi-bin/prnh/20050117/FLMLOGO ) These second-generation quarter-brick IBCs are the result of an intensive on-going development program in very high power density converters. Artesyn launched its first Typhoon quarter-brick IBCs less than 18 months ago, which at the time set an industry benchmark. The new models employ a radically improved conversion topology to maximize efficiency, thermal performance, power throughput and output voltage regulation, resulting in significantly higher performance. Each IBC generates a single isolated 12V output, intended primarily for powering multiple non-isolated point-of-load (POL) converters via an on-board intermediate voltage bus. The products have a significantly lower "cost-per-watt" than standard brick type dc-dc converters, providing designers with highly cost-effective DC power sources for distributed power applications. The IBC38AQT fixed ratio DC transformer has an input range of 42 to 53Vdc, and can generate up to 37.5A at 12V. This unregulated, open loop chopper-type converter provides a very cost-effective solution for applications with well- regulated 48V supply voltages, or for feeding general-purpose wide input POL converters, which can tolerate some supply variation. Typically, fixed ratio IBCs are used for cost-sensitive applications in the computer, storage and server markets. Artesyn is also introducing two application-optimized quarter-brick IBCs with semi-regulated outputs, primarily for boards that have an unregulated supply voltage, or for powering high performance POL converters, which tend to require more tightly controlled input voltages than general-purpose models. The IBC28AQW features a wide industry-standard 36 to 75Vdc input for telecom applications, while the IBC30AQS has a narrower 42 to 53Vdc input suitable for datacom applications. Both models generate an isolated 12Vdc output and use closed loop control techniques to provide tight output regulation. The IBC28AQW can deliver up to 28A while the IBC30AQS has an even higher 30A capability, and either model can be paralleled for very high current applications. All three IBCs have an industry-standard pin-out and 2.3 x 1.45in footprint and are based on an open-frame, single-board package designed for through-hole board mounting. There is a choice of two body heights -- the low profile version has an installed height of just 0.40in, which is ideal for system racks with very tight card pitches. Artesyn's second-generation quarter-brick IBCs use an advanced, patent- pending full bridge conversion topology, combined with special component layout and thermal design techniques, to maximize efficiency, power density and reliability. All three models are designed for operation over a wide ambient temperature range of -40 to +85 degrees Celsius, and are suitable for both convection cooled and forced air environments. They carry a full set of international safety approvals, including UL/cUL60950-1 and EN60950-1 VDE, and are comprehensively protected against fault conditions. Artesyn's Typhoon quarter-brick IBCs are available for immediate delivery. In OEM quantities of 1000, unit prices are US$62.70 for the 37.5A fixed ratio model, US$65.90 for the 30A narrow-input model and US$73.25 for the wide-input 28A model. Standard lead-time on all three products is stock to 8-10 weeks ARO. Typhoon(TM) is a trademark of Artesyn Technologies, Inc. About Artesyn Technologies, Inc.
