原来AMC 7135这么小啊！
<P>昨天找到家有零售AMC 7135、7150的商家，联系后商家与我同在上海就直接打款过去了。没想速度挺快，今天一早货就到手上了，拿到手一看，晕！7135原来这么小啊，我那把大头的电烙铁俺是没本事焊了，今天下班还要去买吧细头的，呵呵！</P><P>上张对比图，毒物终于到手了，哈哈~ </P>
<P>商家卖7135还送外围元件in4148，服务挺周到的。 </P><img src="attachments/dvbbs/2005-10/20051019916280939.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-10/20051019916280939.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /><BR> 管子是5mm的，对比amc7135，好小啊！ <P>太小也不好,带负载发热啊.</P>
还行吧，我准备直接焊在led的铝基片上试试，而且7135带过热保护的，问题不大 <P>用它来做什么？升压稳压管子？</P> <P>这个上面的兄弟看看介绍吧，俺就是那里买的，简单的来说是个恒流驱动芯片，无须外围元件，2.7V--6V输入，350mA输出</P>

1个7135带1个1W的LED正好。呵呵。<IMG src="http://www.shoudian.org/Skins/Default/emot/em01.gif"> <P>恩，是的，正好适用。</P>
<P>尖头的小烙铁俺也买到了，现在正在焊呢，嘿嘿</P> 小烙铁俺是把它磨成刀头的!当然有尖头的最好了! 太好了，用在1W上正好 。 <P>顶！</P>
<P>焊好没？</P> <P>焊好了，因为7135很小巧所以我把7135直接焊LED的铝基片上了，这样散热问题就解决了。</P>
<P>初步测试了一下，用上7135后led的发热比原来小了，现在长时间后led也只是温温的，毕竟恒流了，而且相比原来直接用电阻限流想必效率要高很多了吧，总的来说还是满意这块小小的ic驱动的！</P> <font color="#000000"><span lang="ZH-CN" style="color:red;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn"><p class="MsoNormal" style="margin:0cm 0cm 0pt"><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">电压高于</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">6v</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">可能烧毁</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">,</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">如果电压低于</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">2.7v</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">会怎样</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">? e: </font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">还会有作用吗</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">(350ma), <p></p></font></span></p><p></p><p></p><p class="MsoNormal" style="margin:0cm 0cm 0pt"><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">想把它改装在</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">AA</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">与</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">14500</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">共用电池上</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">,</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">不知可以吗</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">,</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:'times new roman';mso-hansi-font-family:'times new roman';mso-fareast-language:zh-cn">谢谢</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">^^ <p></p></font></span></p><p></p><p></p><p class="MsoNormal" style="margin:0cm 0cm 0pt"></p></span></font> <p>电池电压低于LED VF值时，输出电流会急速下降。。。。</p><p>低于2。5V时。输出可能会极低，类似于关断状态/。</p> <span style="color:red;font-family:新細明體;mso-ascii-font-family:&quot:;times new roman&:;quot:;mso-hansi-font-family:&quot:;times new roman&:;quot:"><p class="MsoNormal" style="margin:0cm 0cm 0pt"><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:&quot:;times new roman&:;quot:;mso-hansi-font-family:&quot:;times new roman&:;quot:;mso-fareast-language:zh-cn">意思是说只能使用</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">14500,2.7v</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:&quot:;times new roman&:;quot:;mso-hansi-font-family:&quot:;times new roman&:;quot:;mso-fareast-language:zh-cn">以下是不行的</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">,</font></span><span lang="ZH-CN" style="color:black;font-family:新細明體;mso-ascii-font-family:&quot:;times new roman&:;quot:;mso-hansi-font-family:&quot:;times new roman&:;quot:;mso-fareast-language:zh-cn">谢了</span><span lang="EN-US" style="color:black;mso-fareast-language:zh-cn"><font face="Times New Roman">.<p></p></font></span></p></span> <div class="quote" twffan="done"><b>以下是引用<i>bp500</i>在2005-10-21 18:41:24的发言：</b><br /><p>焊好了，因为7135很小巧所以我把7135直接焊LED的铝基片上了，这样散热问题就解决了。</p><p>初步测试了一下，用上7135后led的发热比原来小了，现在长时间后led也只是温温的，毕竟恒流了，而且相比原来直接用电阻限流想必效率要高很多了吧，总的来说还是满意这块小小的ic驱动的！</p></div><p></p><font size="4">效率没有提高，只是电流小了，所以发热减小了。</font>
