D-CAP and D-CAP2 control schemes have been widely used in TI Switched-Mode DC-DC converters due to their fast transient response and no off-chip compensation. Offset generated by current sense ramp adds an error to VFB and Vout and hence reduces DC accuracy. This paper introduces a new D-CAP3 control scheme which greatly improves DC accuracy of the converter while maintaining the same fast transie - SMT Guidelines for Stacked Inductor (Inductor On Top) on Voltage Regulator ICPDF, 409 Kb, Archivo publicado: feb 22, 2016
