The TPS65032001-Q1 and TPS65033x-Q1 family of PMICs are configurable and programmable only through I2C instructions. The BOOSTXL-TPS65033 socketed board is designed to act as a BoosterPack to the low cost TI LaunchPads, enabling a LaunchPad to act as the USB-to-I2C interface for communication with a personal computer. This separation reduces the cost of prototyping and enables experimentation with various TI devices, including custom software development using existing LaunchPad tools. Many of these tools can be found online at TI DevTools. The programming GUI is also available in the TI DevTools Gallery. This GUI is compatible with both the MSP430F5529LP and the MSP432E401Y LaunchPads.

The BOOSTXL-TPS65033 is designed to stack on top of a LaunchPad, connecting the relevant power and MCU pins to the PMIC through the headers J1/J3 and J2/J4. Power is delivered to the PMIC from the USB port of a PC through the the LaunchPad 5 V and 3.3 V rails. The following block diagram demonstrates how the LaunchPad interfaces with the PC and the PMIC.
