Artesyn Technologies Inc. has extended its point-of-load (POL) converter range with the introduction of the C-class, non-isolated dc-dc converters that provide a single output, and are designed for cost-critical applications through open-frame, single-board construction.

The SIL20C and SIL40C POL converters feature wide adjustable outputs of 0.9V to 5V, and extend the available output power from 150W to 200W, allowing developers to accommodate changes in power budget without re-designing their PCBs.

Both converters are intended for through-hole board mounting, and are offered in a choice of vertical or horizontal package orientations. Vertical models feature small-footprint, single-in-line connections, enabling developers to achieve high component placement densities if headroom is available.

The SIL20C is the smaller of the POL converters, and can handle output currents up to 20A. The horizontal version measures 30.5-by-27.9mm and has an above-board height of 11.9mm, while the vertical version has a footprint of 30.5-by-10.2mm and an above-board height of 27.9mm.

The SIL40C converter can handle output currents as high as 40A, using a dual-phase switching topology to minimize input and output ripple. The horizontal version measures 60.9-by-31.75mm and has an above-board height of 12mm, while the vertical version has a footprint of 60.9-by-12.7mm and has an above-board height of 31.7mm.

Both products offer remote on/off facility, trim, and a "power good" output signal. The converters have no minimum load requirement, and incorporate over-temperature protection as standard. The converters feature input under-voltage lockout, and are fully protected against overcurrent and short circuit conditions. Operating temperature range is between 0C and 50C.

Pricing for 10,000-piece quantities is $8 for SIL20C and $12.80 for SIL40C. Lead time is 6 to 8 weeks.
