Convertors squeeze 100W into
eighth-brick outline
Artesyn Technologies has extended its Typhoon family of board mounted power with the addition of a new 100W series of eighth-brick DC/DC convertors.
Artesyn Technologies has extended its Typhoon family of board mounted power with the addition of a new 100W series of eighth-brick DC/DC convertors Known as the "ultra" series, which push eighth-brick performance to unprecedented levels, the new convertors provide single isolated outputs of 2.5, 3.3 and 5.0V, with continuous current ratings of 40, 30 and 20A, respectively

All three convertors provide exceptionally high efficiencies and power densities - the 5.0V model, for example, has a typical efficiency of 92% and achieves in excess of 9.8W/cm3.
The 100W ultra series provides a 35% improvement in power capability over second generation, eighth-brick products and up to 200% improvement over earlier first generation competitor offerings.
Artesyn's new ultra series eighth-brick convertors are intended primarily for high-end telecomms applications such as mobile/optical switches, high capacity network routers and similar systems using distributed power architectures.

Comprehensive catalogue features wide range of new AC/DC and DC/DC products.
Their very high current, efficiency and power density attributes, combined with fast transient response capabilities, make them especially suitable for high functionality cards designed around the latest low-voltage silicon.
These new eighth-brick models are lower cost, more space-efficient alternatives to earlier-generation 100W telecomms-compatible quarter and half bricks.
They occupy just 62% of the card space of industry-standard quarter bricks but have the same pinout, enabling designers to start migrating to higher performance, smaller form factor convertors without making any changes to the circuit or card layout.
The convertors feature a wide input voltage range of 36 to 75V DC, and generate a single output voltage which can be adjusted from 80 to 110% of nominal using a single resistor.
They have no minimum load requirement, and provide a true monotonic startup characteristic under both normal and prebiased load conditions, significantly simplifying design-in.
The patented conversion topology - used for all Typhoon brick convertors - eliminates the need for optocouplers and combines advanced processor control of both primary- and secondary-side circuitry with precision synchronous rectification.
The result is a high efficiency, wide bandwidth design that provides excellent regulation and transient response characteristics.
The convertors have a setpoint accuracy of +/-1.5% and maintain output voltage regulation to within 0.1% for all input voltages in the range 36 to 75V, and to within 0.2% for all permissible load currents.
Transient response performance is equally impressive: the output of the 2.5V, 40A convertor, for example, typically deviates by just 90mV for a 1A/us step change in load current and will totally recover within 20us.
As with all Typhoon family eighth-brick convertors, the new 100W ultra series models have an industry-standard 22.9 x 58.4mm footprint and are based on an open-frame, single-board package designed for through-hole mounting.
Extensive use of surface-mount components and planar, in-the-board transformer structures minimises device profile, allowing the installed height to be kept to just 7.6mm.
This exceptionally low figure makes the convertors especially suitable for applications using very tight interboard spacing, such as latest-generation telecomms switches and optical metro routers.
The convertors offer remote sense and remote on/off facilities as standard, and have a typical startup time of 10ms when driving a resistive load.
They also feature undervoltage lockout, as well as nonlatching overvoltage protection, and are comprehensively protected against short-circuit and over-temperature conditions, with automatic recovery.
The convertors carry a full set of international safety approvals, including EN60950 VDE and UL/cUL60950.
Sample quantities of Artesyn's wide-input 100W ultra eighth-brick convertors are available for immediate delivery.
In OEM quantities of 1000, unit prices are US $64.90.
Standard lead-time is 8-10 weeks ARO.
