Optimising Processing Real Estate

The drive to create metadata processing server systems plus the parallel push for increased port density and triple-play (voice/video/internet) traffic handling in telecommunication systems places greater demands on power management architectures. The problem: inefficient power architectures Traditional designs using AC to 12 Vdc Silver Box followed by 12 V to 1.x Vsynch buck have run aground in terms of system power density and efficiency due to a combination of distribution bus losses and fundamental restrictions in topology performance as processor voltages reach sub-volt levels. Higher voltage (48 V or 350/380 V) bus voltages reduce...
