摘　　要：DC-DC电压转换芯片在电子系统和产品中得到了广泛应用。一般,开关电源初学者习惯照搬数据手册上的参数设计电路,而对该电路背后深层次的理论知识知之甚少。该文将“信号与系统”课程的零极点知识运用到电流模式开光电源的控制理论当中,提出了设计一个小纹波降压转换器的具体思路和方法。通过本案例的学习,一方面将认识到“信号与系统”课程的实际应用价值,同时也将认识到电路是设计出来的,而非照抄照搬。DC-DC voltage conversion chips are widely used in electronic systems and products.In general,beginners of switching power are used to copying the parameter design circuit in the data manual,but little is known about the deep theoretical knowledge behind the circuit.In this paper,the zero-pole knowledge of Signal and System course is applied to the control theory of current mode switching power supply.Through the study of this case,the students will realize the practical application value of the Signal and System course,and also the students will realize deeply that the circuit is designed rather than copied.
