System Power Paths
3.2
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 RT9466). This path supports those applications with Li-
Polymer batteries.

These two paths can be selected by J2322 and J2323. We provide two jumpers, 2 Ampere current rating for
each. Usually, any one of them can meet the requirement for most cases.
