思旺电子推出内置唆使灯驱动电路的恒流恒压电源办理IC－SE1052

      Aug 8^th , 2008 –明天，专业电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)办理IC供给(ji)商思旺电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子（Seaward Electronics Inc.）推出(chu)内(nei)(nei)置唆使灯驱(qu)动电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)的恒流(liu)(liu)(liu)恒压(ya)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)办理IC－SE1052。 该(gai)IC是(shi)(shi)(shi)SE1051的进级版本(ben)(ben)，SE1052能够供给(ji)恒定并且精准(zhun)的电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)和电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压(ya)节制，是(shi)(shi)(shi)开关电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)中(zhong)首选的公用集成电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu). SE1052 是(shi)(shi)(shi)特地(di)为1-5节锂电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池停止(zhi)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)所设(she)(she)想(xiang)的低本(ben)(ben)钱计划，SE1052内(nei)(nei)部(bu)集成唆使灯驱(qu)动电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，这个(ge)特别的电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)能够精确监督(du)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的变更。当恒流(liu)(liu)(liu)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)时，SE1052将点亮(liang)(liang)白(bai)色LED；当充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(d♊ian)(dian)(dian)(dian)流(liu)(liu)(liu)减小到预设(she)(she)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)的1/10时，红灯燃(ran)烧(shao)，绿(lv)灯点亮(liang)(liang)，表(biao)现电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池已布满。完成以上提到的一切(qie)的功效，均不(bu)须要多于的核心(xin)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，SE1052已内(nei)(nei)部(bu)集成。SE1052很是(shi)(shi)(shi)合适(shi)利(li)(li)用于数码相机(ji)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，手机(ji)充(chong)(chong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器，适(shi)配器上的利(li)(li)用。

      SE1052恒流功效：SE1052内部的电流采样电路与一个集成运算缩小器构成一个精准的电流节制电路，来完成恒定电流和过流掩护功效。而最大限定电流（I_limit）能够经(jing)由过程调理Rsense阻值的巨(ju)细来设置。计(ji)较公式(shi)以𓆏下：

      此中V_sense=110mV为牢固的电压，而I_limit为设想请求的电流。

      SE1052的恒压的功效：SE1052实物的规范输出功率控制电路板与个结合运算缩短器涉及个精细的输出功率合理控制电路板，使SE1052的基点输出功率改变在1.210V。大家专门针对构想的提起，是可以依靠环节设备两大实物电阻器的阻值的细节来调理改善出所目前的录入输出功率，算计公试有以下一样：

      SE1052的唆使灯保健作用：SE1052企业内部的的有一个运算降低器也可以发放和驱程企业内部的的冲电唆使节能灯。能用于今时领域上支脉的冲电唆使体例：冲电时绿灯亮，充饱电后绿灯亮。岂但为客应该削减了体系化元元器，也为客PCB节流区域。       SE1052有着轻意填补，录入过流无球，用至少的本质元元器提交顾客应该要的功较，好用的为普通用户精打细算原产挣到。

SE1052的首要特色:

l         内部管理集成式恒压恒流合理包块 l         处理器内部管理嵌有精准扶贫的对比电流源 l         内部组织集成式蓄电唆使灯集成运放 l         较小的内部管理电容器 l         集合过流保护效率 l         既然填补 l         ESD可耐防静电2KV l         生成物不含汞、靠谱RoHS实验室管理标准
