一种具有增强电流模式控制和先进保护电路的单片高性能降压转换器

A monolithic high-performance step-down dc-dc converter for high power point-of-load application is presented in this paper. A novel adaptive quadratic slope compensation method and an adaptive antijittering ramp scheme are proposed to enhance the performance of widely used peak current-mode control. A fast overcurrent detection method together with a robust driver control logic design has been in...
