Introduction
CPUs used in notebook computers and other mobile applications now draw more than 30A of current and may draw as much as 65A in the near future. For these heavy loads, high efficiency power supplies are required to protect the system from excessive thermal stress. With this in mind, PolyPhase switching DC/DC converters have become the standard for CPU power supplies ...
