2号LED,VF低一些,因3.0几伏时进入了低电压保护,无法测试大电流参数,

如果测试结果精确的话,那么似乎效果很不错哦,建议测试下低档时的效率

效率很好,等待成品中。。。

theninthlife 发表于 2009-1-9 23:57

有2个问题,1是为啥1a输出时候电压是3.5,到500ma的时候反而3.8了呢?2是为啥到了100ma档效率随电压下降反而上升,和前2档效率变化情况不同

1A的时候测试的两只LED的测试数据,后面的只测试了一只低VF的LED,还有在100MA时随电压下降效率反而上升这应该是这个芯片的特性吧,

呵呵,看来是我没看仔细,这个芯片特性很奇怪哦,期待成品出现,效果似乎不错,加油哦,如果能预估一下成本就最好了,哈哈

什么时候有成品啊。说实话,等东城的3454已经等的不耐烦了。都几个月过去了还没点动静。

LZ一定要加快进度啊。

价格在45,因TPS63000的价格太高了,且不好焊接

lz有时间的话详细介绍下调光方式呗,强烈需求低-中-高并且断电复位的,后面再有个爆闪也能接受,低档要够低,30ma足够,中档350标准,高档700-1000随意
