肖先生在1999年1期所登“最新开关电源集成电路TOP212YA1在松正VCD机应用的剖析和检修”一文中,及时地通过实物测绘,向广大读者提供技术资料和理论依据,对广大维修人员无疑是一种贡献。但肖先生在绘制“TOP系列集成电路内部框图”和“分析短路过流保护”过程时有失误的地方。为防止误导,笔者在此谈谈个人的看法,并对该机电源的检修作一些补
Mr. Shaw in 1999 1, “the latest switching power supply integrated circuit TOP212YA1 in Songzhong VCD machine application analysis and repair,” a text, in a timely manner through physical mapping, to provide readers with technical information and theoretical basis, the majority of maintenance personnel Undoubtedly a contribution. However, Mr. Shaw made some mistakes in drawing up the “Internal Circuit Diagram of TOP Series Integrated Circuits” and “Analyzing Short Circuit Overcurrent Protection”. In order to prevent misleading, I would like to talk about personal views and make some repairs on the machine’s power supply
