Original Press Release:
Power Breakthrough - World's First 200 W Quarter-Brick DC/DC Converters
Up to 100A from 0.3in high module with industry-standard 2.3 x 1.45 in footprint.
Fully regulated output, up to 92% efficiency & unprecedented 200 W/in3 power density
FRAMINGHAM, Mass., November 9, 2004 -Artesyn Technologies Inc. (Nasdaq:ATSN) has extended its leadership Typhoon(TM) family of board mounted power with the addition of a new 200W series of quarter-brick DC/DC converters. Known as the 'ultra' series, which push single-board, quarter-brick performance to unprecedented levels, the new converters provide single isolated outputs of 2.5V, 3.3V and 5.0V, with continuous current ratings of 80A, 60A and 40A, respectively. All three converters provide exceptionally high efficiencies and power densities - the 5.0V model, for example, has a typical efficiency of 92% and achieves in excess of 200W/in3. The 200W 'ultra' series provides up to a 50% improvement in power capability over present competitor offerings.
The 200W converters have an industry-standard quarter-brick footprint of 2.3 x 1.45in and a height of just 0.3in. They provide an extremely cost-effective functional replacement for half-bricks, occupying 40% less board space and delivering much higher levels of output current and useable power. The converters are intended primarily for the networking, telecom and wireless markets, in applications as diverse as core routers and switches, transmission systems, and optical networking. Their exceptionally high current, efficiency and power density attributes, combined with their very low profile, make them suitable for delivering the 200W power requirements of fully specified cards in AdvancedTCA® applications.
The new 'ultra' series 200W quarter-bricks feature a wide telecom-standard input voltage range of 36 to 75VDC and generate a single isolated output voltage, which can be trimmed from 80% to 110% of nominal using a single resistor. Flexibility of design-in is further enhanced by the availability of two additional low-voltage 100A models, offering a choice of 1.5V at 100A and 1.8V at 100A outputs, to address virtually all of today's low-voltage silicon supply needs.
The 200W quarter-bricks are the latest additions to Artesyn's rapidly expanding Typhoon(TM) family of high performance board-mounted DC/DC converters. They use the same patented conversion topology as all other Typhoon bricks, which combines advanced processor control of both primary- and secondary-side circuitry with precision synchronous rectification, and eliminates the need for optocouplers. This topology helps maximize efficiency and bandwidth, resulting in excellent regulation and transient response characteristics. Unlike intermediate bus converters (IBCs) and DC-DC transformers, which only achieve high efficiencies and power levels by generating loosely regulated or unregulated outputs, Artesyn's new 200W quarter-bricks feature fully regulated outputs for driving low-voltage silicon loads directly. All five converters have a set-point accuracy of ±1.5% and maintain line and load regulation to within ±0.1% and ±0.2% respectively.
Typhoon 200W quarter-bricks are based on an open-frame, single-board package designed for through-hole mounting. Primarily intended for use in forced air environments, they operate over a wide ambient temperature range of -40 to +85˚C and do not require a heatsink. Surface-mount components and planar, in-the-board transformer structures are employed to minimize device profile, maximize reliability and facilitate automated assembly to help keep manufacturing costs as low as possible. Additionally, the 60/80/100A devices have adopted the new high-current industry-standard pin-out option referred to as 'The double P', or THermally Enhanced Double Power Pins. It includes an additional set of power and ground pins for sharing the current flow, which addresses many board-level manufacturing issues that can arise when attempting to route more than 50A through a single plated through-hole or via. See website for more details.
The converters offer differential remote sense and remote on/off facilities, and have a typical start-up time of 10ms when driving a resistive load. They also feature undervoltage lockout, as well as non-latching overvoltage protection, and are comprehensively protected against short-circuit and overtemperature conditions, with automatic recovery. The converters carry a full set of international safety approvals, including UL/cUL60950 and EN60950-1 VDE. They also meet the rigorous EN61000-4-6 EMC standard for conducted emissions and the telecom-standard input transient rating of 100V for 100ms, which is beneficial in reducing customers' system qualification time and accelerating their time-to-market.
Sample quantities of Artesyn's 200W quarter-brick converters are available for immediate delivery. In OEM quantities of 1000, unit prices are US$ 88.00 for all models. Standard lead-time is stock to 8-12 weeks ARO. For further information about Artesyn's new Typhoon 200W quarter-brick converters, please visit: http://artesyn.com/powergroup/new_brick_launch.htm
