Cost Effective Power Management Design for Advanced PC Motherboards

In such a rapidly changing information industry, it is essential to speed up the clock speed of CPU. Without increasing power dissipation, the required voltage for core part (Vcore ) in CPU such as INTEL’s Pentium, Pentium II, Pentium III, AMD’s K6 and K7 is keeping declining at the expense of increasing in current. To meet this requirement, the design of power converter on mother board has been changed into a Multiple Output Integrated Regulator instead of using the traditional Linear Regulator, Asynchronous Voltage Step-Down Regulator and Synchronous Voltage Step-Down Regulator. To go along with this trend, “Analog Integrations Corporation” introduces a new IC product AIC1570 that provides more integrating functions with higher performance and lower system cost.
