Artesyn Technologies Inc. (Boca Raton, FL) announced the launch of the first products in its new Typhoon TM family of dc/dc converters. All products in the Typhoon TM family employ patent-pending power conversion technology, and provide best-in-class, breakout performance in four categories: output current capability, efficiency, height and cost. At launch, the family comprises a single-output, eighth-brick converter capable of delivering up to 40A at 1.8V, and two dual-output, quarter-bricks offering 20A per channel.
All converters in the Typhoon TM family are based on an open-frame, single-board package, specifically designed for operation without a heatsink. The converters use synchronous rectification and advanced control techniques to maximize efficiency and transient response, and employ surface-mount components and planar, in-the-board, transformer structures to limit height to just 0.3in (7.7mm). All the converters feature 48V inputs and isolated outputs, making them suitable for telecom systems employing distributed power architectures.
The Typhoon single-output, eighth-brick converter, the first product in the series, is a 1.8V output model designed for through-hole mounting, capable of delivering up to 40A. It has an efficiency of 89 percent at full load, giving a power density figure in excess of 180W/in³. Future Typhoon TM models will include 1.2V, 2.5V and 3.3V output configurations. Power design engineers can now substitute a 40A quarter-brick with a 40A eighth-brick, reducing the converter footprint by 38 percent and the cost by as much as 25 percent.
The Typhoon TM dual-output, quarter-brick converters offer 3.3V/1.2V or 3.3V/1.8V output configurations, and are designed for through-hole mounting. Both models feature independently regulated outputs, with each channel capable of delivering up to 20A, and have an efficiency of 90 percent at full load. Future Typhoon TM models will include 3.3V/2.5V and 5.0V/3.3V output configurations. Power design engineers can now replace two 20A quarter-bricks with one dual-output, 20A quarter-brick, reducing the converter footprint by 50 percent and the cost by as much as 25 percent.
Pricing for 1,000-piece quantities is $64.50 for the single-output, eighth-brick converters, and $92 for the dual-output, quarter-brick converters.
