摘要
在Dr.Sam Ben-Yaakov开关电感模型概念的基础上,根据DC/DC模块TPS54310的实际工作原理,建立适用于SPICE软件的状态空间平均模型,从而可以方便地对TPS54310进行直流分析、小信号分析以及闭环大信号瞬态分析。模型的准确性在所建模型的SPICE仿真结果与TI公司提供的专用设计软件SWIFT^(TM) Designer 2.01的设计结果的对比中得到证实。
Based on the Switched Inductor Model (SIM) concept of Dr. Sam Ben-Yaakov an averaged SPICK model of the TPS54310 is built using equivalent circuit method. So the DC analysis, small signal analysis and large signal closed loop transient analysis of the TPS54310 can easily be done. The validity of the model is verified by comparision between the results of design with the original design program SWIFF?Designer 2. 01 and the results of SPICE simulation using the model built.
