Supply keeps processors cooking

By Bill Schweber -- EDN, September 30, 2004

Today’s microprocessors need more than micropower to operate. To get that needed power, you might consider the Artesyn Technologies VRM10 series of nonisolated point-of-load converters (Picture). The converters meet Intel specifications for powering the Xeon and Pentium processors. They provide 85A continous current and 100A peak current with transient response of 930A/μsec. The four-phase buck-conversion architecture operates at 2.2 MHz with efficiency as high as 86% at 85A/1.4V load. Each supply sells for $35.25 (1000).
