Identifying this chip—high efficiency main power supply controller?

Hello,

I believe this is a Richteck RT8205LZQW but I am not sure. The chip definitely says "EM DJ" new line "???". According to Richteck the EM is the product and the DJ and part that cannot be read is the the date code, but I am leery of assuming that my chip is the same. It is from a Toshiba and as you can clearly see, is quite fried.

Also, does anyone have any suggestions on how to track down what the !&&* these types of things are? Specifically, in a way that is easier and more efficient than searching the internet for the few markings you can find?

Thanks for any help and suggestions.

Mr. Doldrum
