摘　　要：本文首先对BUCK拓扑结构和CUK斩波电路进行分析，阐述了基于芯片ISL6420B和LT3580的双路输出DC／DC变换器。其次根据理论参数计算，选择辅助器件，并对电路中的主要功能进行仿真，结合实际调试，完善电路设计。最后，给出实验结果和波形。In this paper,firstly the circuit about BUCK and CUK configuration are analyzed, the design of DC/DC converterwith two different outputs based on ISL6420B and LT3580 is described. Secondly,theoretical parameters are calculated,the auxil-iary devices are selected,and the main function of the circuit simulation is performed,combined with actual adjusting,circuit de-sign is improved. Finally,the experimental results and waveforms are given.
