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
