The Ethernet LaunchPad development kit can be powered from three different input options:
The JP1 power-select jumper is used to select one of the power sources.
In addition, the 3V3 Jumper on J101 power jumper can be used to isolate the 3.3-V output of the TPS79601 in the XDS-110 emulator from the 3.3-V rail of the target side.
A TPS2052B load switch is used to regulate and control power to the Target USB connector when the microcontroller is acting in USB host mode. This load switch also limits current to the BoosterPack plug-in module and Breadboard adapter headers when the JP1 jumper is in the XDS-110 position.
