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.

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.

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.

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.

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.

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.

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.

模糊動(dòng)態(tài)規(guī)劃法（FDP）的提出是為了解決配電站的無(wú)功功率、電壓控制問(wèn)題。主要目的是提高二級(jí)總線上的電壓分布以及同時(shí)抑制主變壓器的無(wú)功功率流入。為了達(dá)到我們的目標(biāo)，變壓器分接頭通常安裝在主變壓器上，用來(lái)調(diào)整二次電壓，連接在二級(jí)總線上的電容器用來(lái)補(bǔ)償負(fù)荷所需求的無(wú)功潮流。我們首先預(yù)測(cè)主變壓器的有功和無(wú)功的功率要求以及第二天的主電壓。利用手邊的預(yù)測(cè)數(shù)據(jù)，快速地產(chǎn)生了一個(gè)ltc分接頭位置的估算公式，這個(gè)估算公式考慮了負(fù)荷模型，有效地降低了該方法的計(jì)算負(fù)擔(dān)。把對(duì)母線電壓的實(shí)際限制，一天之中主電壓器的ltc開關(guān)操作所允許的最大次數(shù)和電容器承受的最差功率因素都納入了考慮。為了證明該方法的有效性，對(duì)臺(tái)北市臺(tái)灣電力公司的辦公服務(wù)區(qū)域內(nèi)的配電站電壓無(wú)功控制進(jìn)行了研究。結(jié)果表明，可以通過(guò)此方法對(duì)ltc和電容器進(jìn)行適當(dāng)?shù)恼{(diào)度。

如何正確導(dǎo)入Spice模型方法一、將模型文件粘在當(dāng)前的圖紙上，方法見(jiàn)圖：步驟1：復(fù)制模型文件（米源于OrCAD PSpice Model）步驟2：將復(fù)制的文件復(fù)制到下圖所示位置步驟3：點(diǎn)擊上面框圖中的OK，將文件粘貼在紙面上，然后從文件中拖一個(gè)三極管出來(lái)，將名字改成一樣即可。方法二、如有*.1ib的庫(kù)文件，比如PSPICE的日本晶體管庫(kù)jbipolar.lib，將該文件考到ltc LTspicelV\lib\sub目錄中。然后按圖操作：方法三：將模型文件直接粘貼到ltcYLTspiceIV\ib\cmp中的相應(yīng)文件中。如要將PSPICE的diode.lib的模型全導(dǎo)入到cmp中的standard.dio中。先用記事本打開diode.1ib，全選，復(fù)制。而后用記事本打開standard，dio，在其適當(dāng)?shù)奈恢谜迟N，關(guān)閉。發(fā)現(xiàn)二極管庫(kù)里多了很多元件（見(jiàn)下圖）。三極管同理。
