Abstract

Power source requirements for systems employing high performance microprocessors are analyzed and possible solutions are presented. Analysis and simulation show that the optimum converter switching frequency is dependant on the type of output capacitor used, which is generally selected to meet size versus cost goals. Proportional loop compensation is shown to result in a smaller peak to peak transient output voltage excursion than integral compensation. A new pair of ICs are introduced which are optimized for this application
