POL converters are open framed

Artesyn Technologies has launched three new families of single-output, non-isolated point-of-load (POL) converters designed for use in computer workstations, PCs, servers and data storage devices.

Known as the SIL06, SIL15 and SIL30 Series, these DC/DC converters employ an open-frame single-board construction.

All three families are intended for through-hole board mounting and offer a choice of vertical or horizontal package orientation to simplify design-in.

The SIL06 Series is the smallest of the new POL converters, and can handle output currents up to 6A. The horizontal mounting version measures just 1.2 x 0.61 inches (30.5 x 15.5mm), and has an above-board height of 0.53 inches (13.4mm); the vertical mounting version has a footprint of only 1.2 x 0.45 inches (30.5 x 11.3mm), with an above-board height of 0.61 inches (15.5mm).

There are two models in the series, with nominal input voltages of 5VDC and 12VDC. The 5V input model has a typical conversion efficiency of 89% and provides an output that is trimmable from 0.9V to 3.3V. The 12V input model offers even higher conversion efficiency – typically 91% – and an exceptionally wide output trim range, spanning 0.9V to 5.0V.

Artesyn’s SIL15 Series POL converters handle output currents of up to 15A. The horizontal mounting version measures 1.2 x 1.1 inches (30.5 x 27.9mm), and has an above-board height of 0.47 inches (12mm); the vertical mounting version has a footprint of 1.2 x 0.4 inches (30.5 x 10.2mm), with an above-board height of 1.1 inches (27.9mm). There are two models in the series, with nominal input voltages of 5VDC and 12VDC. The 5V input model has a typical conversion efficiency of 89% and provides an output that is trimmable from 0.9V to 3.3V. The 12V input model has a typical conversion efficiency of 91%, and an output trim range of 0.9V to 5.0V.

The new SIL30 Series POL converters can handle output currents as high as 30A, using a dual phase switching topology to minimise input and output ripple. The horizontal mounting version measures 2.4 x 1.35 inches (60.9 x 34.3mm), and has an above-board height of 0.47 inches (12mm); the vertical mounting version has a footprint of only 2.4 x 0.5 inches (60.9 x 12.7mm), with an above-board height of 1.25 inches (31.7mm). The converter has a nominal input voltage of 12V, a typical full load efficiency of 91%, and an output that is trimmable over the range 2.5V to 5.0V. The SIL30 also features remote sense capabilities, allows current sharing between parallel modules, and incorporates over-temperature protection as standard.

All SIL06, SIL15 and SIL30 Series POL converters offer a remote on/off facility and a ‘power good’ output signal. The converters have no minimum load requirement, and are capable of sinking as well as sourcing current, for termination applications. They feature input under-voltage lockout, and are fully protected against over-current and short-circuit conditions.

Artesyn’s SIL06, SIL15 and SIL30 Series POL converters have an operational temperature range of 0 degrees C to +50 degrees C ambient, and carry a full set of international safety approvals, including EN60950 and UL/cUL60950.
