The convertors are expressly designed for use with standard low voltage 3.3 and 5.0V onboard bus levels, enabling the power stage to operate with optimised duty cycles for maximum conversion efficiency; they employ synchronous buck topology, using fixed-frequency switching and ultra low on-resistance mosfets.
The target application areas of the new SIL10 series are principally those that demand very small footprint, high reliability power sources capable of operating over a wide temperature range, such as optical network and wireless infrastructure components and systems.
At launch, the SIL10 series of POL convertors comprises eight fixed-output models and one wide output trim model.

The fixed-output convertors offer voltages of 0.8, 1.0, 1.2, 1.5, 1.8, 2.0, 2.5 or 3.3V, and accommodate any input voltage in the range 3.0 to 5.5V.
The wide output trim model requires a 4.5 to 5.5V input, but its output can be adjusted from 0.8 to 3.6V using a single resistor; Artesyn has included this model so that electronics designers can begin to use this latest-generation POL conversion technology, even if the voltage requirements of some of the ICs in their designs are likely to change in the near future - thus providing maximum flexibility to electronics designers.
All SIL10 series POL convertors employ an open-frame, single-board construction to minimise cost and weight and simplify thermal management.
They are constructed entirely from surface-mount components, including the magnetic devices, and are designed for fully automated assembly to help keep manufacturing costs as low as possible.
All the convertors in this series are designed for through-hole board mounting - they have industry-standard pinouts - and are fully compatible with PIHR (pin-in-hole reflow) processes, making them ideal for manufacturers who are seeking to simplify production or move towards more environmentally-friendly processes by eliminating wave soldering.
SIL10 convertors are available with a choice of vertical or horizontal package orientation to simplify design-in.
The horizontal mounting version measures 2.0 x 0.5in (50.8 x 12.7mm), and has an above-board height of only 0.32in (8.1mm); the vertical mounting version features single-inline connections and has a minimal footprint of just 2.0 x 0.31in (50.8 x 7.8mm), with an above-board height of 0.5 inches (12.7mm).
The extremely low above-board height of both versions of convertors makes them ideal for high-end telecomms applications, which tend to use tight inter-board rack spacing to minimise system size.
Furthermore, their exceptional efficiency and ultracompact dimensions means that Artesyn's SIL10 series convertors have the highest power density of any comparable POL product on the market, achieving an industry-leading figure of 107W/in3.
All SIL10 series POL convertors accommodate a wide operational temperature range of -40 to +85C ambient, and are expressly designed as high reliability products, using very conservative component derating criteria.
The convertors feature remote sense and remote on/off facilities, have no minimum load requirement, and are comprehensively protected against overtemperature, undervoltage and short-circuit conditions.
They carry a full set of international safety approvals - including EN60950 (TUV Product Service) and UL/cUL60950 - and meet the EN55022 level A standard for radiated emissions.
According to Mark O'Sullivan, Artesyn Technologies' Product Manager for Low Power DC/DC Convertors, "We are now seeing an increasing use of onboard power conversion, driven mainly by designers' needs to accommodate the diverse voltage requirements of today's ICs, coupled with ever-decreasing voltage levels.
In fact, many designers are now having to use a fairly sophisticated form of distributed power architecture, involving both isolated and nonisolated DC/DC convertors, just to satisfy the power demands of individual boards.
The market for nonisolated POL convertors is set to grow significantly, and we believe that by developing industry-leading products like the SIL10, we will be well positioned to meet our customers' requirements".
