'''

C2005 (Top right capacitor): '''A capacitor that is used for the BUCK0_LX0 output of U2000 (PM IC) to ground and this is on the PP_CPU line. Also used to filter out ripple on the PP_CPU line.

C2088 (Top left capacitor):

A capacitor that goes to ground and is used to filter out ripple on the PP_VCC_MAIN power line

C2121 (Bottom right capacitor):

This is also another capacitor that goes to ground, does the same thing for above.

C2127 (Bottom left capacitor) :

This is also another capacitor that goes to ground, does the same thing for above.

C2005 capacitor details:

15UF

20%

6.3V

X5R

0402-1

C2088 capacitor details:

10UF

20%

6.3V

CERM-X5R

0402-9

C2121 and C2127 capacitor details:

10UF

20% (Efficiency I'm assuming?)

CERM-X5R (Ceramic Capacitor)

0402-9 (Size of component)

Used for power management unit (PM IC chip).

Note that one or more capacitors can be shorted on these lines so if you are checking these capacitors for shorts, check all of them on the line.

PP_CPU has about 11 capacitors (C2000-C2910)

PP_VCC_MAIN has about 15 capacitors (C2085-C2099)
