SSD Component Search

[ddrecovery]

I have a Samsung SSD MZ-KPU1T0T/0A6. It was water damaged in one corner. I can see one component has a crack through the top of the chip and had corrosion around the legs, so presumably the crack was caused by a short. I am having difficulty tracking down what this component might be. Marking are:-

PSR1
43K
C8ST

I am guessing buying one may not be an option, so perhaps using a donor may be the way to go, but wanted to see if anyone (@fzabkar?) might be able to shed light on what component we are looking at.

TPS61086, Texas Instruments, 18.5V PFM - PWM Step-Up DC-DC Converter with 2A Switch, 2.3V - 6.0Vin, VSON-10, marking PSRI:

I would measure the resistance of the capacitor to the left of the diode ("5").

If the NANDs require a +12V supply, then maybe you could patch it into the circuit from an external source?

Thanks for the link. I have now searched an found the component and have it on order. Probably safer than patching 12v into the NAND. We can approach this again if this part doesn't solve the issue. Diode mode reading on the cap by the way was 540.

Thanks again.
