The V_IN scope and V_OUT scope test points can be used to monitor V_IN and V_OUT waveforms with an
oscilloscope. These test points are intended for use with un-hooded scope probes. The scope probe tip
should be connected to the socket labeled VIN or VOUT, and the scope ground barrel should lean against
to the test point labeled GND. The GND TP may need to be cut or bent slightly to hold the probe barrel.

The control test points located directly below the TPS84x10 IPS device are made available to test the
features of the device. Any external connections made to these test points should be referenced to either
of the two control ground test points located along the bottom of the EVM. Refer to Section 4 of this user
guide for more information on the individual control test points.
The V_OUT-select and F_SW-select configuration jumpers are provided for selecting the desired output voltage
and appropriate switching frequency. Before applying power to the EVM, ensure that the jumpers are
present and properly positioned for the intended output voltage. Refer to Table 2 for the recommended
jumper settings. Always remove input power before changing the jumper settings.
Once the jumper settings have been confirmed, configure the host input supply to apply the appropriate
bus voltage listed in Table 2 and confirm that the selected output voltage is obtained.
