三种具有快速动态响应的VRM拓扑分析比较

Analysis and Comparison of Three Topologies for VRM Fast Transient Application

本文给出了三种具有快速动态响应速度的VRM拓扑:多相交错Buck拓扑、采用步进电感的变换器拓扑、混合供电模式拓扑。并分析了它们各自的设计目标、工作原理.以及各自的优缺点。

This paper proposes three topologies for VRM fast transient application：multi phase interleave Buck topology, stepping inductor converter, hybrid sources. Analysises the key point and principle about each technology, and compares each other.
