一种用于电流模式DC-DC降压变换器的高精度限流方案

Peak current-mode dc–dc buck converters are widely used in the low-to-medium power applications. Although some current-limiting schemes have been proposed to raise current-limiting accuracy, the deviation of current-limiting threshold caused by bandwidth limitation of current-sensing scheme and inherent propagation delay remains unsolved. Targeting on inaccurate current-limiting threshold under va...
