Introduction
Notebook computers demand more power than ever before, and in turn, CPU supply current requirements have grown significantly to the point where the latest Intel mobile CPUs call for up to 40A. Such high currents reveal many design problems that are relatively insignificant at lower current levels. Today’s notebook power supply designer must successfully manage the inevitable resulting power losses and thermal stresses within the already tight notebook ...
