requiring an ultra-fast response from the power supply. To obtain higher clock speeds and to enhance manufacturing yields, the Pentium requires specific output voltage levels with tight voltage regulations (Figure 3). Within this stringent voltage regulation limit, no overshoot or undershoot are permitted to exceed the regulation limit, irrespective of their duration. Not surprisingly, these new demands have overwhelmed the capabilities of existing power supply designs based on conventional PWM.
