Digital Power Management Reduces Energy Costs While Improving System Performance

August 30, 2014 // By Andy Gardner, Linear Technology
Today's designers of networking equipment are expected to push the limits of performance and add functionality under the pressure of vanishingly short development times and tight cost constraints. Increasing network system functionality adds ASICs and processors, each requiring several voltage rails, resulting in line cards with dozens of rail voltages. The challenge with so many rails is to optimize hardware utilization so that overall power consumption is minimized.
