Today, six-phase converters running at 1 MHz per phase, using 2-mΩ MOSFETS and 100-nH SMT inductors to deliver 150A at 1V are no longer a novelty. However, they are relatively inefficient and cannot ...
Multiphase buck topology is preferred for processors that are drawing increasing amounts of current at lower voltage. Common design practices limit the open-loop bandwidth of the control system to 10% ...
The evolution of motherboard power systems has always been a challenging environment from both a cost and performance standpoint. This is particularly true for the CPU Vcore power control. Over the ...
