摘要
以LM5117芯片和CSD18532KCS为核心器件,设计并制作了一个降压型直流开关稳压电源,电路中采用仿真电流斜坡的电流模式控制,得到了较高的输出稳定度和较小的纹波。电源具有过流保护和负载识别功能。通过仿真与实验得到了较理想的电源参数。
This paper designed and produced a step-down dc switching power supply,with LM5117 chips and CSD18532 KCS as the core devices. Current slope of current mode control circuit adopts the simulation,the higher output stability and smaller ripple are obtained. The power supply has the function of over-current protection and load identification. Through the simulation and experiment,the ideal power supply parameters are obtained.
