- Accuracy-Enhanced Ramp-Generation Design for D-CAP3 Modulation (Rev. A)PDF, 493 Kb, 修订版: A, 档案已发布: Apr 25, 2016
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 - Not All Jitter Is Created Equal (Rev. A)PDF, 555 Kb, 修订版: A, 档案已发布: Jul 4, 2015
This application report offers a tutorial discussion on jitter in switching DC-DC converters. Not all power supply designs are equally susceptible to jitter, nor are they equally affected by jitter. Modes of switching jitter are defined and explained for several popular control architectures, which are then analyzed for sources of jitter. An example contrasting the amount of jitter and effect on o - SMT Guidelines for Stacked Inductor (Inductor On Top) on Voltage Regulator ICPDF, 409 Kb, 档案已发布: Feb 22, 2016
