Post subject:	KinDian SSD burned components
Hi, Well I had used the wrong cabe to connect power to my ssd when changing the PSU ... Now I have a piece of PCB with no use ... After a magnifier use and detailed look at the PCB i figured out that I burned some commponents ... The first one is 3012 .743J4, and the second 3013 ... Is there any help to replace the parts,and to help me find out what parts are the 3012 .743J4 and the 3013 (I asume some dc/dc converters,but didn't find any with this code) ??? Is there any chance to connect via JTAG pins and download the data from the drive ??? I'm a hobist electronic,and have some equipment to try to fix this drive,but all sugestions are welcome ... cheers, Darko

Thx ... Any info where I can buy the parts ?? Would the JTAG read the data ??? What for a JTAG programmer do I need ... would an ST-LINK V2 be OK ??? cheers Darko

I haven't found a source for those chips. Instead I would try to find compatible pinouts from more common sources such as TI and Monolithic Power. Alternatively, you could determine the output voltage of each regulator (by measuring the feedback resistors) and then substitute a DC-DC converter module. I don't know what could be achieved via JTAG, but that question is moot if the PCB is dead.
