Press Release Summary:
Rated for full usable power at 85°C, 100 LFM, 10 and 15 A converters have 0.9 x 2.3 in. footprint and are based on open-frame, single-board package designed for through-hole mounting. They provide conversion efficiencies of 92% and feature input voltage range of 36-75 Vdc. Products generate single, 5 V isolated output, adjustable over range of 4-5.5 V via single external resistor. With no minimum load requirement, converters have typical start-up time of 10 ms.
Original Press Release:
5V Output Eighth-Brick DC/DC Converters Raise Efficiency Stakes to 92%
Ideal cost- and space-saving replacements for quarter-bricks
Rated for full usable power at 85°C, 100LFM
Framingham, MA, June 8, 2004 - - Artesyn Technologies Inc. (Nasdaq:ATSN) has launched two new 5V single output eighth-brick DC/DC converters which provide industry-leading conversion efficiencies of 92%. Forming the latest additions to the company's renowned Typhoon(TM) family of high performance board-mounted power conversion products, the new converters are available with current ratings of 10 and 15A now, and 20A in the near future, enabling designers to choose the most cost-effective model for their particular application. They are the ideal power solution for today's tightly-packed boards - designers can now replace a standard 5V quarter-brick with a lower cost, higher performance eighth-brick module, and gain a 38% saving in board real estate.
Both of these new eighth-brick converters feature a wide input voltage range of 36 to 75VDC and generate a single 5V isolated output, adjustable over the range 4 to 5.5V via a single external resistor. Design-in flexibility is further enhanced by the fact that the converters have no minimum load requirement, and provide a true monotonic start-up characteristic under both normal and pre-biased load conditions. The converters feature remote sense and remote on/off facilities as standard, and have a typical start-up time of 10ms when driving a resistive load. Synchronous rectification and advanced processor control of both primary- and secondary-side circuitry maximize efficiency and transient response. The 15A model, for example, has a very high power density - in excess of 120W/in³ - and its output voltage deviates by just 92mV for a 1A/µs step change in load current and will totally recover in less than 20µs.
As with all Typhoon family eighth-brick converters, the new 5V output models have an industry-standard 0.9 x 2.3in (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 minimizes device profile, allowing the installed height to be kept to just 0.3in (7.6mm). This exceptionally low figure makes the converters especially suitable for applications using very tight inter-board spacing, such as latest-generation telecom switches and optical metro routers.
Artesyn's 5V eighth-brick converters are designed for operation over an ambient temperature range of -40 to +85°C without a heatsink. Their ultra low profile construction minimizes airflow disruption and makes them suitable for both convection cooled and forced air environments. The converters feature under-voltage lockout, as well as non-latching over-voltage protection, and are also protected against short-circuit and over-temperature conditions, with automatic recovery. The converters carry a full set of international safety approvals, including EN60950 VDE and UL/cUL60950.
According to Todd Hendrix, Vice President of Worldwide Marketing for Artesyn, "Although eighth-brick converters account for a small portion of brick usage today, they are now beginning to proliferate in new system designs. Our Typhoon family of high performance eighth-bricks, for example, are proving very popular in the communications sector. The ultra low profile, high power density attributes of these converters are considered key for high component density cards in tightly-stacked racks. The introduction of these new models means that we now offer more than a dozen different eighth-bricks covering voltages from 1.2 to 5V, giving designers considerable freedom to migrate from quarter-brick products."
Sample quantities of Artesyn's 5V eighth-brick converters rated at 10A and 15A are available for immediate delivery, and the standard lead-time for quantity orders is stock to 12 weeks. Pricing for 1000-piece quantities starts at $49.50 US for the 10A part, and $57.56 US for the 15A version.
