带同步电流模式滞环控制的单电感多输出调整器

Abstract

本发明提供了一种带同步电流模式滞环控制的单电感多输出调整器,其为具有快速瞬态响应的电流模式滞环模式控制技术的单电感多输出(SIMO)直流到直流开关转换器以抑制交叉调制。此直流到直流开关转换器包含:至少一个功率源,用于提供电子能量;电感性能量存储元件,用于从输入功率源积累电子能量和传输电子能量到多个输出;主开关,用于控制在电感性能量存储元件中的能量积累;多个输出开关,用于对能量传输到多个输出中的每一个输出进行控制;续流开关,其与电感性能量存储元件并联;以及控制器,配置好以协调多个输出开关和主开关。A single-inductor-multiple-output (SIMO) DC-DC switching regulator with a current-mode hysteretic control technique having an ultra-fast transient response to suppress cross-regulation is provided. The DC-DC switching regulator includes: at least one power source for providing electrical energy; an inductive energy storage element for accumulating and transferring the electrical energy from the input power source to a plurality of outputs; a main switch for controlling energy accumulation at the inductive energy storage element; a plurality of output switches for controlling energy transfer to each of the plurality of outputs; a freewheel switch coupled in parallel with the inductive energy storage element; and a controller, configured to coordinate the plurality of output switches and the main switch
