Getting Started: Multiple EVM Evaluation
1. Connect Power to one EVM and remove the jumpers on all EVMs shorting VBUS and VSYS. All VCCA
and GND power pins are shared between the stacked EVMs.
2. Connect one EVM to the Host PC through the USB. In the event that the power is provided by the USB
cable, apply the appropriate jumper connection to connect VBUS and VSYS see
.
3. Stack Master EVM and Slave EVM(s). For convenience it is recommended to place the Master on the
top of the stack.
4. Launch the GUI and evaluate.
The EVM can be powered solely from the 5 V USB connection (either 5V VUSB or 3.3V USB_3V3),
provided that the total load is less than 3 W. This removes the requirement for a separate supply when
evaluating a number of the digital features of the PMIC with the EVM.
The three distinguishing characteristics of the slave EVM are the PMIC, the backside components
described in
, and the jumper position on J37. With the jumper on J37 placed in the slave position,
the ENABLE pin of the slave PMIC is connected to the VOUT_LDOINT output pin of the master PMIC
through the J29 Stack-up header. Once the master and slave devices are stacked, supplying power on J6
is the only requirement for getting started. VSYS_IN is connected to VCCA and distributed across all
stacked boards through J28. The power supply can be applied to any of the available J6 terminals.

The GUI Tool
Texas Instruments provides a GUI tool to enable, configure, and evaluate the various features of the
TPS6594x-Q1 with the EVM. Please refer to the GUI User's Guide
for a more detailed
description of this tool.
