TI PS54394 (100% Quality PNG)

Every Texas Instrument IC I have opened so far uses copper connection points. This has been a serious pain for me because these connections are much harder to melt and detach from the plastic package. These ones in particular are much thicker than normal, even after I got it detached from the package, the copper traces were STILL connected and the chip was hanging on for dear life. I had to manually break them, which leaves large sections of the wires protruding from the surface of the die. This makes cleaning a nightmare, and it confuses my camera's focus.

 

The remaining debris you see are mostly plastic residue - which I cannot remove due to the darn copper wires!

 

Texas Instrument's website describes this as a "3A Dual Channel Synchronous Step-Down Switcher with Integrated FET". I have no idea what that means, so here is the data sheet www.ti.com/lit/ds/symlink/tps54394.pdf

 

I believe this is some sort of power delivery IC and as the name suggests it is capable of handling 3 amps, which would explain the relatively large wires.
