  • 運用LT3092電流源以高線性度來實現溫度至電流轉換

      One of the fi rst lessons in a basic electronics coursecovers the symbols for resistors, capacitors, inductors,voltage sources and current sources. Althougheach symbol represents a functional component of areal-world circuit, only some of the symbols Have directphysical counterparts. For instance, the three discretepassive devices—resistors, capacitors, inductors—canbe picked off a shelf and placed on a real board muchas their symbolic analogs appear in a basic schematic.Likewise, while voltage sources Have no direct 2-terminalanalog, a voltage source can be easily built with an offthe-shelf linear regulator.

  • LT1010在電源緩沖區中的應用

      A frequent requirement in systems involves drivinganalog signals into non-linear or reactive loads. Cables,transformers, actuators, motors and sample-hold circuitsare examples where the ability to drive diffi cult loads isrequired. Although several power buffer amplifi ers areavailable, none Have been optimized for driving diffi cultloads.

  • 信號源,調節器和電源電路分析

      Occasionally, we are tasked with designing circuitry for aspecific purpose. The request may Have customer originsor it may be an in-house requirement. Alternately, a circuitmay be developed because its possibility is simply tooattractive to ignore1. Over time, these circuits accumulate,encompassing a wide and useful body of proven capabilities.They also represent substantial effort. These considerationsmake publication an almost obligatory propositionand, as such, a group of circuits is presented here. This isnot the first time we Have displayed such wares and, giventhe encouraging reader response, it will not be the last2.Eighteen circuits are included in this latest effort, roughlyarranged in the categories given in this publication’s title.They appear at the next paragraph.

  • PCMCIA卡和卡插槽的電源管理系統

      Most portable computers Have built-in sockets to acceptsmall PC cards for use as extended memories, fax modems,network interfaces, wireless communicators and awide assortment of other functions. The Personal ComputerMemory Card International Association (PCMCIA)has released specifications that outline the general powerrequirements for these cards.

  • P54C-VR奔騰(R)微處理器的電源模塊

      Providing power for the Pentium® microprocessor family isnot a trivial task by any means. In an effort to simplify thistask we Have developed a new switching regulator controlcircuit and a new linear regulator to address the needs ofthese processors. Considerable time has been spent developingan optimized decoupling network. Here are severalcircuits using the new LTC®1266 synchronous buck regulatorcontrol chip and the LT®1584 linear regulator toprovide power for Pentium processors and Pentium VREprocessors. The Pentium processor has a supply requirementof 3.3V ±5%. The Pentium VRE processor requires3.500V ±100mV.

  • Designing Linear Circuits for 5V Operation

      In predominantly digital systems it is often necessaryto include linear circuit functions. Traditionally, separatepower supplies Have been used to run the linear components(see Box, “Linear Power Supplies—Past, Present,and Future”).

  • 電流檢測電路手冊

      Sensing and/or controlling current flow is a fundamental requirement in many electronics systems, and the tech-niques to do so are as diverse as the applications them-selves. This Application Note compiles solutions to cur-rent sensing problems and organizes the solutions by general application type. These circuits Have been culled from a variety of Linear Technology documents

  • Wide-input dc/dc modules offer

    When a system designer specifies a nonisolated dc/dc powermodule, considering the needed input voltage range isequally as important as considering the required performanceattributes and features. Generally, nonisolated modulesHave either a narrow or a wide input voltage range. Narrowinputmodules typically Have a nominal input voltage of3.3, 5, or 12 V. For systems that operate from a tightlyregulated input bus—such as those that do not use batterybackup—a narrow-input module is often adequate sincethe input remains fairly stable.Offering greater flexibility, wide-input modules operatewithin a range of 7 to 36 V, which includes the popular12- or 24-V industrial bus. This enables a single module tobe used for generating multiple voltages. These modulesare ideal for industrial controls, HVAC systems, vehicles,medical instrumentation, and other applications that usea loosely regulated distribution bus. In addition, systemspowered by a rectifier/battery charger with lead-acidbattery backup almost always require wide-input modules.System designers who choose power supplies may wantto take a close look at the latest generation of wide-inputdc/dc modules.
