Eden Prairie, Minn. - Artesyn touts its DDR12 point-of-load dc/dc converter as the first such unit to address the specialized dual-voltage, source-and-sink requirements of all double-data-rate synchronous DRAMs.
Intended as an all-in-one power solution to the widely used two-converter (or equivalent) approach, the DDR12 delivers both the 2.5-volt VDDQ potential for the DDR logic and the 1.25-V DDR termination voltage (VTT) in a single module. As a result, the company says, designers can reduce implementation costs by as much as 40 percent.
This open-frame, nonisolated converter, with a footprint of 3 x 0.51 inch and an above-board height of 1.2 inches, is packaged as a vertically oriented module suitable for use in dense 1U-high rack-mount applications. Typically, these include workstations, servers and communications infrastructure equipment, as well as general-purpose computing and industrial applications. The converter's single-in-line connections are intended for through-hole board mounting.
The DDR12's 2.5-V VDDQ output delivers up to 25 amps, and its VTT output up to 8 A, from a nominal 12-V input (10.8- to 13.2-V range).
The DDR12 employs synchronous-rectification techniques and delivers 85 percent efficiency at half load or greater. The module is rated for operation over 0 degrees C to 80 degrees C, suitably derated. It carries a full set of international safety approvals, including EN60950 and UL/cUL 60950. Pricing is $16.75 each in quantities of 10,000, and lead time is stock to eight weeks.
