摘　　要：SG3525是一种性能优良、功能齐全、通用性强的单片集成脉宽调制控制器。由于它简单可靠及使用方便灵活,大大减化了脉宽调制器的设计及调试。文中介绍了集成芯片SG3525的特点和主要功能;给出了由SG3525组成的推挽式DC/DC直流变换器的系统结构设计;用实验数据和结果说明了设计的可行性。SG3525 is a kind of monolithic integrated PW-M controller with excellent performance, complete function and high universality. Because it is simple, reliable and easy to use , its design and debugging are greatly simplified. This paper introduces the characteristic and main function of the intergrated chip SG3525. The structure design of the push-pull DC/DC convertor that is composed of SG3525 is given. The feasibility of the design is proved by the experiment data and result.
