Abstract

We present and analyze system-level total ionizing dose (TID) tests of the simple analog system, point-of-load (PoL) dc/dc converter from 3D Plus, which was already qualified up to 50 krad(SiO2) based on component-level tests. TID response varied with the radiation facility for several parts; however, extensive testing with one part has shown significant differences in the TID level of functional failure observed for different operation modes (configurations): depending on the operating configuration of the device, the observed TID level of failure varies from about 60 krad(SiO2) to more than 400 krad(SiO2). These differences are depicted with the use of the safe operating area (SOA) plot for the system, which incorporates main system functional parameters. We also explore the potential utilization of the SOA concept in defining the system’s TID performance, employing a range of TID thresholds rather than relying on a singular value.

TID 故障级别与系统运行配置的关系--空间级 DC/DC 转换器案例研究

我们介绍并分析了对 3D Plus 的简单模拟系统、负载点 (PoL) 直流/直流转换器进行的系统级总电离剂量 (TID) 测试。几个部件的 TID 响应随辐射设施的不同而变化；然而，对一个部件进行的广泛测试表明，在不同操作模式（配置）下观察到的功能故障 TID 水平存在显著差异：根据设备的操作配置，观察到的故障 TID 水平从大约 60 krad(SiO2) 到超过 400 krad(SiO2) 不等。这些差异可以通过系统的安全运行区域图（SOA）来描述，其中包含了主要的系统功能参数。我们还探索了利用 SOA 概念定义系统 TID 性能的可能性，采用了一系列 TID 临界值，而不是依赖于一个单一的值。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
