请看LUXDRIVE的LED驱动模块1000mA BUCKPUCK，国内能不能找到有类似功能的IC？

<P>这个驱动模块所具备的连续调光功能，想必是大家都喜欢的。</P>

<P>不知道楼上要用在什么地方，有现成的IC可以做到</P>

我行我色 发表于 2005-9-14 14:38

<P>5.5V~7V输入驱动3W，可连续调光（参见应用的Figure9和Figure11），请推荐。</P>

用AMC7150就可以做到，

我行我色 发表于 2005-9-14 16:37

<P>微桥的7150实现连续调光有困难，0.22~3欧姆的电位器就不好找.</P>

可以改一下电路啊，不要人家出那样的电路就那样用

<P>愿闻其详，谢谢！</P>
