摘要
设计制作了一款基于LT1083/LT1033系列大功率低压差三端稳压芯片的高稳定度低纹波直流电源,介绍了降压、整流滤波、线性稳压、LC低通滤波等主要构成模块。测试结果表明,本电源具有输出电压稳定度高、输出电流大、低纹波、低功耗等特点。
The paper designs and manufactures a power supply with high stability and lower ripple based on low-dropout voltage three-terminal chip. It introduces the main structure including voltage reduced module, rectified filter module, linear regulator module, low pass filtering module. To software-based, the experimental results show that the high performance on output voltage fluctuant, output current,ripple as well as low loss.
