Can anyone identify the burned chip on this circuit board? It is a Chinese motorcycle dashboard, but the design is probably from Kawasaki Rouser. The chip might not be burned, but one pin is broken so I want to try replacing it with a new one, but have no idea what it is...
It is a 5V LDO linear regulator, seemingly NCV4275A. Here is what it should look like if it weren't half burned:
The burned trace and bulged 50V 220µF capacitor are on the input side; the two 100µF 16V capacitors appear to be on the output. The former will definitely have to be fixed along with the replacement of this regulator, but, as Olin points out, there may be more extensive damage that isn't visually apparent.
This unit is toast. Replacing the one obviously burnt chip will not fix the problem, and may just cause the new chip to get blown up too. Something bad happened to this board, which clearly caused more than one chip to be damaged. Get a new one and this time don't short the output, hook it up the wrong way to the battery, or whatever caused the problem.
Note the vaporized trace to the left of the top electrolytic capacitor. A lot of current went thru there. A little bit of the copper is still left near the capacitor. I also don't like the bulging top of the cap, and the fact that this is apparently a no-name type without a vent. When it goes, it's going to take a lot more stuff with it.
Put another way, the burnt chip is just one symptom of a much larger problem.
