App note: High voltage adjustable power supplies

  TI application note (PDF!) on high voltage adjustable power supplies: An improved approach is shown in Figure 2. Here an LM329B 6.9V zener reference has been stacked in series with the LM317’s internal reference. This both improves temperature stability, since the LM329B has a guaranteed TC of ±20 ppm/˚C, and improves regulation, because more […]

App note: Latency in factory automation

An app note (PDF!) from Texas Instruments on importance of latency in factory automation: Latency is a critical parameter in Ethernet networks developed for Factory Automation applications.  Latency is not a defined value for Ethernet as specified by the IEEE 802.3 standard. Nor is Ethernet inherently synchronous or repeatable. This disconnect between the inherent characteristics of Ethernet and the needs […]

App note: AN-42 IC provides on-card regulation for logic circuits

This application note (PDF!) from TI provides on-card regulation for logic circuits: Because of the relatively high current requirements of digital systems, there are a number of problems associated with using one centrally-located regulator. Heavy power busses must be used to distribute the regulated voltage. With low voltages and currents of many amperes, voltage drops in […]
