  This ink marks LTC’s eighth circuit collection publication.1We are continually surprised, to the point of near mystification, by these circuit amalgams seemingly limitlessappeal. Reader requests ascend rapidly upon publication,remaining high for years, even decades. All LTC circuitc ...

In August of 1992 LTC published Application Note 49, “Illumination Circuitry for Liquid Crystal Displays.” One notable aspect of this event is that it generated more response than all previous LTC application notes combined. This level of interest, along with significant performanc ...

  For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...

为了改变目前电网现场作业管理的变电巡检、变电检修试验、输电线路巡检检修等管理系统各自独立运行，信息不能共享，功能、效率受限，建设和维护成本高的现状，提出了采用B/S+C/S构架模式，将各现场作业管理模块和生产MIS（管理系统）集成为一体的现场作业管理系统的设计方案，做到各子系统和生产MIS软硬资源共享，做到同一 ...
