高速电路传输线效应分析与处理

随着系统设计复杂性和集成度的大规模提高，电子系统设计师们正在从事100MHZ以上的电路设计，总线的工作频率也已经达到或者超过50MHZ，有一大部分甚至超过100MHZ。目前约80% 的设计的时钟频率超过50MHz，将近50% 以上的设计主频超过120MHz，有20%甚至超过500M。当系统工作在50MHz时，将产生传输线效应和信号的完整性问题；而 ...

Solutions for LED Driver Overvoltage Protection

Boost LED drivers are often used to drive LEDs in series. If an LED fails while open,overvoltage protection (OVP) is necessary to avoid the damage to a boost integrated circuit (IC) or output capacitor. This application report presents the solutions to increase the TPS61043 LED driver OVP threshold.

电源工程师-电路设计中的英雄

Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, ...
