Hi guys,
I am trying to identify this SMD IC (U8 in the photo). I think its some kind of dc/dc converter, voltage detect IC.

The markings on the IC are:
0304
6CJ
PF36
I think the ‘PF36’ is the important bit. I was able to find similar kind of ICs with PF36 but nothing which really matched to the package type or the marking.

The dimensions of the package is:
3mm x 3mm
There are total of 10 pins (5 on each side) plus the ground on the bottom it does peak out from the sides as well.
What is this package type?
I have this faulty unit which does not power up. It has got a ‘soft power switch’. It gets stuck half way during power up sequence. Trying to troubleshoot this section of the circuit. I have included a picture of this section which I have started to trace, maybe it might be of help.

Thanks in advance for the help

 

Package is SON/DRC-10
Link to part/datasheet here:

0304 is the important part here. That is part number identifier.
6CJ is most likely year/month/site
PF36 is lot number

QFN and SON packages can be hard to identify. The markings are different with each manufacturer
