2、0.5W的，電壓是2.5-3.77V，電流是150mA。

3、1W的，電壓是2.79-3.99V，電流(liu)是320-350mA ，選驅動一(yi)般是選300mA電流(liu)的，芯片大小30mil 、35mil、 40mil、 45mil。

4、3W的，電壓是3.05-4.47V，700mA ，驅(qu)動一般600mA ，芯片(pian)大小45mil 。

5、5W的，電壓是3.16-4.88V，電流是1000mA。

一般用(yong)(yong)作(zuo)照明用(yong)(yong)的(de)LED燈珠由0.5w-5w的(de)都(dou)有， 工作(zuo)電壓在3-3.2V左右。

白光LED1瓦燈珠參(can)數是多少，我們一般設計(ji)是3.6---4.2V，0.2---0.3A。

電(dian)壓：3.2-3.6v，電(dian)流(liu)300-350ma，光通(tong)量：100-120流(liu)明，色溫：白光6000-7000K

led燈芯片型號哪些

目前，芯片設(she)(she)計(ji)行業越來越多的廠家加入了LED設(she)(she)計(ji)，設(she)(she)計(ji)出眾(zhong)多型號，在此從性能價格比方(fang)面詳細的談(tan)談(tan)，怎樣選擇自(zi)己(ji)合適的IC，哪(na)些(xie)ICZ合適自(zi)己(ji)準(zhun)備設(she)(she)計(ji)的產品。

為(wei)IC設計(ji)企業(ye)了解市場需(xu)要什么樣的(de)IC，應該(gai)制(zhi)定(ding)什么價(jia)位中合適。價(jia)格(ge)隨時會變動只能為(wei)參考值。質量和價(jia)格(ge)是決(jue)定(ding)是否(fou)采用的(de)因數(shu)，符合產(chan)品設計(ji)質量參數(shu)要求很重(zhong)要價(jia)格(ge)更(geng)重(zhong)要

1、美(mei)國CATALYST公(gong)司-CAT4201

 這(zhe)個(ge)IC驅動(dong)1-7顆1W LED。效率可達92%，6-28V電(dian)壓輸入范圍降壓型驅動(dong)應用設(she)計(ji)。比前面兩款(kuan)ICZ大(da)的優(you)勢(shi)是封(feng)裝SOT23大(da)小，線路簡介，符合目前多數小體積(ji)燈杯設(she)計(ji)使(shi)用要求。

大(da)阻值范圍(wei)電(dian)流調節，可以電(dian)位器(qi)寬(kuan)阻值范圍(wei)調節亮(liang)度，比(bi)如設(she)計臺燈等(deng)產品需(xu)要(yao)這樣時。

2、美國國家半導體 LM3404

LM3404和LM3402的線(xian)路一樣，不同的是電流(liu)可(ke)以達到1A，驅動1-15pcsLED性價比(bi)較(jiao)高。

上(shang)面所列(lie)IC規格都是(shi)內置(zhi)MOS管，內置(zhi)MOS管可以簡化線路(lu)設(she)計(ji)(ji)(ji)，小(xiao)體積(ji)，降(jiang)(jiang)低設(she)計(ji)(ji)(ji)綜(zong)(zong)合成本(ben)，故障率(lv)也會(hui)(hui)降(jiang)(jiang)低。因(yin)其目前IC工(gong)藝(yi)制成、成本(ben)等(deng)原因(yin)大于1A以上(shang)的(de)LED驅動IC需(xu)要外置(zhi)MOS管。在我們日常(chang)(chang)產品設(she)計(ji)(ji)(ji)中經常(chang)(chang)會(hui)(hui)遇到(dao)大電(dian)流(liu)設(she)計(ji)(ji)(ji)，比如5W、10W等(deng)更高(gao)功率(lv)的(de)設(she)計(ji)(ji)(ji)要求，那(nei)只能選擇外置(zhi)MOS管的(de)IC才可以。接下來(lai)會(hui)(hui)綜(zong)(zong)合成本(ben)推薦幾款IC，為廣大的(de)工(gong)程師朋(peng)友選型方便。

3、褒貶(bian)不一的LED驅動芯片IC-AMC7150

在當時AMC7150還是(shi)(shi)不錯的(de)，我想(xiang)了想(xiang)還是(shi)(shi)提提，它有個(ge)很重(zhong)要的(de)因數就是(shi)(shi)價(jia)格，有不到2元的(de)市場價(jia)格，是(shi)(shi)你(ni)采用它的(de)理由。AMC7150目(mu)前有幾十家可以(yi)直(zhi)接替換的(de)IC型號，價(jia)格戰會無法(fa)避免。

在(zai)(zai)設(she)計(ji)參數要求不高的(de)低(di)壓(ya)4-25V產品中可以選擇它，基本驅動(dong)能力(li)在(zai)(zai)3W以下(xia)應(ying)用設(she)計(ji)。比如1W串(chuan)3顆或3W 1顆LED設(she)計(ji)是穩定的(de)。

4、歐(ou)洲Zetex公司-ZXLD1350

這(zhe)顆IC目前市(shi)場反應良好，也是SOT23小體積封(feng)裝(zhuang)，輸入7-30V電(dian)壓(ya)(ya)降壓(ya)(ya)恒流驅動(dong)1-7psc LED，線路(lu)簡潔實用。設計(ji)時Rs要緊靠(kao)IC避(bi)免供電(dian)電(dian)壓(ya)(ya)大(da)幅度不動(dong)，這(zhe)樣會影(ying)響恒流效果。

總體電(dian)子物(wu)料成本要略高于前款(kuan)IC。

5、杭(hang)州士(shi)蘭微電子(zi)-SB42511

目前士(shi)蘭(lan)半導體推出新款IC，主要(yao)(yao)是針對驅動24V驅動6顆LED市場(chang)。價格要(yao)(yao)高于AMC7153優惠于歐美市場(chang)IC，適(shi)合設計1-6顆LED，輸入6-25V輸入電壓，SOP8封(feng)裝形式(shi)，主要(yao)(yao)針對目前低端射燈(deng)市場(chang)。

6、美國美信(xin)集成產(chan)品(pin)公司 MAX16802

MAX16802A/B是高亮度(du)（HB） LED驅(qu)動(dong)(dong)器(qi)控制IC，內部(bu)包含(han)了(le)設計一個寬(kuan)輸入范圍LED驅(qu)動(dong)(dong)器(qi)所需的電(dian)路，適(shi)合通(tong)用照(zhao)明和顯示應用。適(shi)用于低輸入電(dian)壓(ya)（10。8V DC至24V DC） LED驅(qu)動(dong)(dong)器(qi)。需要精密調節(jie)LED電(dian)流時，可利(li)用片(pian)上的誤差放大(da)器(qi)以及精度(du)為1%的基準。通(tong)過低頻PWM亮度(du)調節(jie)可實現較寬(kuan)的亮度(du)調節(jie)范圍。

MAX16802 具(ju)(ju)有(you)輸(shu)入欠壓(ya)(ya)鎖定(ding)（UVLO）特性(xing)，可(ke)(ke)設置(zhi)輸(shu)入啟(qi)動(dong)電(dian)(dian)壓(ya)(ya)，并可(ke)(ke)確保在(zai)電(dian)(dian)源跌落時正常工作。MAX16802具(ju)(ju)有(you)較高滯回電(dian)(dian)壓(ya)(ya)的(de)內(nei)部自舉欠壓(ya)(ya)鎖定(ding)電(dian)(dian)路，從而簡(jian)化(hua)了(le)離線式LED驅(qu)動(dong)器(qi)的(de)設計。MAX16802內(nei)部沒有(you)這個(ge)自舉電(dian)(dian)路，可(ke)(ke)直(zhi)接由(you)+12V電(dian)(dian)壓(ya)(ya)提(ti)供偏置(zhi)電(dian)(dian)源。內(nei)部微調的(de)262kHz固定(ding)開關頻率允許優化(hua)選擇磁性(xing)元(yuan)件和濾波(bo)元(yuan)件，從而實現緊湊、高性(xing)價比的(de)LED驅(qu)動(dong)器(qi)。

MAX16802A的(de)(de)Z大占(zhan)空(kong)比為50%，MAX16802B的(de)(de)Z大占(zhan)空(kong)比為75%。這些器件(jian)均采(cai)用(yong)8引腳μMAX封裝，可工作在-40°C至+85°C溫度范圍。
