System Power Paths

There are two power supply paths for the system. One is through a buck converter (Richtek RT6276A), which convert 12V
(DC Jack) to 4.2V (VSYS). This path supports those applications without Li-Polymer batteries.
The other is through a battery charger IC (Richtek RT9471D). This path supports those applications with Li-Polymer
batteries.
