The buck converter with adopted voltage mode, current mode, constant on-time control, and adaptive on-time control (D-CAPв„ў mode) are discussed in detail in terms of their control methods, and their transient performances. The advantages of the D-CAP mode applicable to the portable applications are presented based on this analysis. The jitter mechanism in the D-CAP mode is studied, and an improveme - Intel Core i7 Arrandale SV and Clarksfield SV Reference DesignPDF, 58 Kb, 档案已发布: Jul 21, 2010
