厦新手机A320上白光LED IC，标记"Y58","551",不知啥型号？

我的一个朋友的手机是厦新A320，屏黑了，其中感觉就是这个IC的第5脚断了导致问题。她把手机弄湿了，结果IC发霉，清洗时脚掉了。其中壳体上两行字，上面一行是“Y58”，下面一行是“551”，希望有朋友给点指导。我在网上查了，但找不到这种的。应该是SOT23-6封装

可以确定不是二极管，因为我平时也做过白光LED驱动电路，我用的大多是6个串联的，发现跟A320中的这个IC很像，但应该不同。此外，这个元件是SOT23-6，也就是说它是6脚的，所以SOT23（三个脚）肯定不是。<br />　　这个IC的第1脚是电感脚，第2脚是地，第3脚是反馈，测到有12ohm左右的对地电阻，第6脚是电源，接电感的另一脚，这和我用的大多数白光LED驱动器很像，比如ZXLD1100，AT1312A等

<br />有可能是用户自已印的代码,那就没戏了<br />&nbsp;<br /><font color=#FF0040>ZXLD1100.PDF资料&nbsp;→</font>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="https://bbs.21ic.com/upfiles/img/20076/2007624194822469.pdf" target=_blank>https://bbs.21ic.com/upfiles/img/20076/2007624194822469.pdf</a><br /><br /><br /><img src="https://bbs.21ic.com/upfiles/img/20076/2007624194228250.gif">

顶

的确，我之前先在这类网站注册了一下，但没积分，没下下来，所以我又问21社区的朋友们来了，呵呵

好像是CAT4137，在便携式太阳能手电筒上有这样的应用。

可A320上面这个IC有6个脚
