how to design multi-phase PWM design (CPU)
becuase AMD or Intel prescott CPU have large current > 60A ..
if we use single pahse PWM need driver very large power-mos

how to design multi-phase PWM system ?? 2 phase or 4 phase is better ?
have any paper (or book) talk about multi-phase PWM circuit

Re: how to design multi-phase PWM design (CPU)
Andy2000a,
I have a thesis named" High density high current fast transient low-voltage DC-DC Converters"
He talks on multiphas design in 3rd chapter.
