SLVUBO3A April 2019 – October 2020 TPS650330-Q1
Both the 5 V and 3.3 V rails connect to the PMIC through separate current limiting load switches. The load switches are simultaneously enabled with the S2 toggle switch on the top left area of the board. See Section 5 for the complete BOOSTXL-TPS65033 schematic. It is recommended to keep S2 open when connecting the LaunchPad to the PC to reduce the initial current draw from the USB port.
