Help with PC motherboard component

[4cx10000]

Hi!

Suddenly the motherboard IPM17-DD HP Envy gave up. I pulled the cover, swapped the PSU but to no avail. I then took my thermal imager and found that an ic, next to the ATX power connector, was running hot by more than 100 degrees C. I have two pictures of this IC (3x3 mm) which I have not found on the webb so I would be very thankful if someone know what it is. By chance, do anyone know where to get hold of a schematic for this motherboard?



Thanks in advance

Bjorn

WOW! Thank you so much wraper! How the he... could you find it so fast?!  I can clearly see the marking information in the datasheet but I searched all over the webb, with every thinkable option, and with no hits at all! 

Thank you once again wraper!

Check ceramic capacitors and mosfets and diodes around that chip ... it may gave failed after another component around it failed.

I googled "88 richtek" because it looked like Richtek.
