Anyone know what this chip is?

here is where it is located on the back of the board and here is the chip itself as you can see it is broken all it says on it is u70 looks like it has something to do with powering the system nand. which would make sense as this switch has a black screen no power.

from memory it’s the backlight driver TPS61162A

confirmed can be replaced with TPS61163A as well

Do you know the chip above that is the can use the same chip? Thanks

no it’s not the same, I’ve been unable to identify that IC, the + symbol on it would indicate it’s a Maxim component but no luck finding it
