    I just took a look on Mouser.com and the IC (fdms8660s) is obsolete, however, if you go to the bottom and hit show similar this is what you get:

    http://www.mouser.com/Search/Refine....425984+1323043

    I would take a look at the datasheet from the fdms8660s which is available here:

    http://www.alldatasheet.com/datashee...FDMS8660S.html

    pay close attention to the pin layout on there and try to find something that is similar in specs and has identical pin out.

    Good luck!!!!

      I use findchips.com.

      This leads to

          Are you sure it's shorted? If it's across vcore and you measure with the CPU in-circuit you might think so but the CPU has a very low resistance and appears like a short circuit across vcore. (Think about it... even with an idle power of ~10W, at a voltage of ~1V that is 10A... 1V/10A = 0.1ohm.)
