System Power Paths

3.2.1

System Power

There are three power supply paths for the system. DC adaptor supply have two paths connect 12V DC adaptor, a buck
converter (Richtek RT6238), which convert 12V (DC Jack) to 4.2V output. The 4.2V output connect two jumpers.
The first path is to short the jumper J50, the 4.2V output is connected to VSYS.
The second path is to short the jumper J44, the 4.2V output is connected to the charger IC (MediaTek MT6360), and then
connected to VSYS through the charger IC.
Note: DO NOT connect the battery in the second path.
The third path is battery power (not verified), the battery power is connected to the charger IC (MediaTek MT6360), and
then connected to VSYS through the charger IC. This path supports those applications using Li-polymer batteries.
