Artesyn Technologies has launched a dual-output non-isolated point-of-load (POL) converter for DDR memory.
Known as the DDR12, this special-purpose POL converter is specifically designed to provide an all-in-one power solution for DDR memory and associated control logic.
Until now, electronics designers have been forced to use two POL converters or complex circuitry based on discrete components, to meet the power needs of DDR memory. The new DDR12 dual-output POL converter offers a cost-effective alternative to both these approaches, by enabling both the 2.5V VDDQ supply for the DDR logic and the 1.25V DDR termination voltage (VTT) to be derived from a single, compact module. It is estimated that this dual-output POL will allow designers to reduce implementation costs by as much as 40%.
The DDR12 employs synchronous rectification techniques and has a high conversion efficiency - typically 85% - when operated at half-load or greater. The 2.5V VDDQ output can deliver up to 25A, while the 1.25V VTT output can deliver up to 8A; both voltages are trimmable from 90% to 110% of their nominal value.
Suitable for use with all DDR-SDRAM devices, the DDR12 converter is packaged as a small footprint, vertically-oriented module suitable for use in 1U-high rack-mount applications. Typically, these would include workstations, servers and communications infrastructure equipment, as well as general-purpose computing and industrial applications.
Pricing for 10,000-piece quantities is US$16.75, and the standard lead time is stock to 6-8 weeks.
