ltc

ltc即L2C[1]（LeadsToCash），是從線索到現金的企業運營管理思想，華為的ltc流程[2]也深入的應用了這一思想[3]，L2Cplat是這一思想的踐行者。是以企業的營銷和研發兩大運營核心為主線，貫穿企業運營全部流程，深度融合了移動互聯、SaaS技術、大數據與企業運營智慧，旨在打造一個從市場、線索、銷售、研發、項目、交付、現金到服務的閉環平臺型生態運營系統。

電源轉換,測量和脈沖電路

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液晶照明技術

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.

ltc1325電池管理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用戶指南

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簡化測量高阻抗傳感器

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一致性測試

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.

配電站電壓無功控制的模糊動態規劃法

模糊動態規劃法（FDP）的提出是為了解決配電站的無功功率、電壓控制問題。主要目的是提高二級總線上的電壓分布以及同時抑制主變壓器的無功功率流入。為了達到我們的目標，變壓器分接頭通常安裝在主變壓器上，用來調整二次電壓，連接在二級總線上的電容器用來補償負荷所需求的無功潮流。我們首先預測主變壓器的有功和無功的功率要求以及第二天的主電壓。利用手邊的預測數據，快速地產生了一個ltc分接頭位置的估算公式，這個估算公式考慮了負荷模型，有效地降低了該方法的計算負擔。把對母線電壓的實際限制，一天之中主電壓器的ltc開關操作所允許的最大次數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，對臺北市臺灣電力公司的辦公服務區域內的配電站電壓無功控制進行了研究。結果表明，可以通過此方法對ltc和電容器進行適當的調度。

如何向LTspice正確導入Spice模型

如何正確導入Spice模型方法一、將模型文件粘在當前的圖紙上，方法見圖：步驟1：復制模型文件（米源于OrCAD PSpice Model）步驟2：將復制的文件復制到下圖所示位置步驟3：點擊上面框圖中的OK，將文件粘貼在紙面上，然后從文件中拖一個三極管出來，將名字改成一樣即可。方法二、如有*.1ib的庫文件，比如PSPICE的日本晶體管庫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中的相應文件中。如要將PSPICE的diode.lib的模型全導入到cmp中的standard.dio中。先用記事本打開diode.1ib，全選，復制。而后用記事本打開standard，dio，在其適當的位置粘貼，關閉。發現二極管庫里多了很多元件（見下圖）。三極管同理。
