The switching power supply was the recent years applies the very widespread one kind of new style power source. This article first introduced switching power supplys research background, the characteristic, the prospects for development, as well as its practical application. Then conducts the research to the switching power supply principle. In has analyzed in the modular DC/DC switching power supply principle foundation, we select ST Corporations L4960 module, according to the correlation technique specification, carries on the design to the switching power supply, carries on the electric circuit schematic diagram in EDA on software PROTEL the design and the PCB electric circuits plan, and completes to electric circuits simulation. 关键词：开关电源 L4960 PROTEL 仿真Simulation 摘 要：现在一般应用的串联调整稳压电源，是连续控制的线性稳压电源，这种传统的串联稳压器，调整管总是工作在放大区，流过的电流是连续的，这种稳压器的缺点是承受过载和短路的能力差、效率低。介绍了开关电源的基本构成以及开关电源的核心部分— — 功率变换器的基本类型，重点介绍了单片开关集成稳压器L4960的内部结构、工作原理并利用IA960设计斩
