According to this image:
The second chip LJ=** is
RT6258CGQUF, is a fixed 8A 5V power supply
Logically R2=** (which remains unknown) is the 3V power supply (you can double-check that, pins 2/3 are outputs & pin 11 should be 3V LDO)
and by looking closely at the pinouts,
RT6258BGQUF is identical which is a fixed 3.3v supply rated @ 8A marked as LE=**
according to the datasheet:
the value of the resistor & caps are: pin6=1Kohm, pin9=1uF, pin10=4.7uF
A closer look on the board reveals that "R2=" uses a 1.5uH inductor while the suggested chip "LE= /RT6258BG" uses 1uH, which means "R2=" as far as I know has a higher rated power "more than 8A"..
let's see the masters opinion if it should work properly
P.S: Found a 10A rated 5V chip "RT6260C" marked "MR=" but no 10A 3V variant could be found..
