  • 电源转换,测量和脉冲电路

      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 circuitcollections, despite diverse content, share this popularity,although just why remains an open question. Why isit? Perhaps the form; compact, complete, succinct andinsular. Perhaps the freedom of selection without commitment,akin to window shopping.

  • 高效LCD液晶照明技术

    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 performance advances since AN-49’s appearance, justifies further discussion of LCD backlighting circuitry.

  • P54C-VR奔腾(R)微处理器的电源模块

      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.

  • ltc1325电池管理IC的使用

      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-stage charging schemes. The majority of batterycharger ICs available today lock the user into one fixedcharging regimen, with at best a limited number ofcustomization options to suit a variety of application needsor battery types. The ltc®1325 addresses these shortcomingsby providing the user with all the functionalblocks needed to implement a simple but highly flexiblebattery charger (see Figure 1) which not only addressesthe issue of charging batteries but also those of batteryconditioning and capacity monitoring.

  • ltc3207,ltc3207-1用户指南

      The ltc®3207/ltc3207-1 is a 600mA LED/Camera driverwhich illuminates 12 Universal LEDs (ULEDs) and onecamera fl ash LED. The ULEDs are considered universalbecause they may be individually turned on or off, setin general purpose output (GPO) mode, set to blink at aselected on-time and period, or gradate on and off at aselected gradation rate. This device also has an externalenable (ENU) pin that may be used to blink, gradate, orturn on/off the LEDs without using the I2C bus. This may beuseful if the microprocessor is in sleep or standby mode. Ifused properly, these features may save valuable memoryspace, programming time, and reduce the I2C traffi c.

  • ADC简化测量高阻抗传感器

      Delta-sigma ADCs, with their high accuracy and high noiseimmunity, are ideal for directly measuring many typesof sensors. Nevertheless, input sampling currents canoverwhelm high source impedances or low-bandwidth,micropower signal conditioning circuits. The ltc®2484family of delta sigma converters solves this problem bybalancing the input currents, thussimplifying or eliminatingthe need for signal conditioning circuits.

  • HDMI一致性测试

      The high defi nition multimedia interface (HDMI) is fastbecoming the de facto standard for passing digitalaudio and video data in home entertainment systems.This standard includes an I2C type bus called a displaydata channel (DDC) that is used to pass extended digitalinterface data (EDID) from the sinkdevice (such as adigital TV) to the source device (such as a digital A/Vreceiver). EDID includes vital information on the digitaldata formats that the sink device can accept. The HDMIspecifi cation requires that devices have less than 50pFof input capacitance on their DDC bus lines, which canbe very diffi cult to meet. The ltc®4300A’s capacitancebuffering feature allows devices to pass the HDMI DDCinput capacitance compliance test with ease.

  • 配电站电压无功控制的模糊动态规划法

     模糊动态规划法(FDP)的提出是为了解决配电站的无功功率、电压控制问题。主要目的是提高二级总线上的电压分布以及同时抑制主变压器的无功功率流入。为了达到我们的目标,变压器分接头通常安装在主变压器上,用来调整二次电压,连接在二级总线上的电容器用来补偿负荷所需求的无功潮流。我们首先预测主变压器的有功和无功的功率要求以及第二天的主电压。利用手边的预测数据,快速地产生了一个ltc分接头位置的估算公式,这个估算公式考虑了负荷模型,有效地降低了该方法的计算负担。把对母线电压的实际限制,一天之中主电压器的ltc开关操作所允许的最大次数和电容器承受的最差功率因素都纳入了考虑。为了证明该方法的有效性,对台北市台湾电力公司的办公服务区域内的配电站电压无功控制进行了研究。结果表明,可以通过此方法对ltc和电容器进行适当的调度。

  • 如何向LTspice正确导入Spice模型

    如何正确导入Spice模型方法一、将模型文件粘在当前的图纸上,方法见图:步骤1:复制模型文件(米源于OrCAD PSpice Model)步骤2:将复制的文件复制到下图所示位置步骤3:点击上面框图中的OK,将文件粘贴在纸面上,然后从文件中拖一个三极管出来,将名字改成一样即可。方法二、如有*.1ib的库文件,比如PSPICE的日本晶体管库jbipolar.lib,将该文件考到ltc LTspicelV\lib\sub目录中。然后按图操作:方法三:将模型文件直接粘贴到ltcYLTspiceIV\ib\cmp中的相应文件中。如要将PSPICE的diode.lib的模型全导入到cmp中的standard.dio中。先用记事本打开diode.1ib,全选,复制。而后用记事本打开standard,dio,在其适当的位置粘贴,关闭。发现二极管库里多了很多元件(见下图)。三极管同理。
