C protocol, and sends the I C signal to the TPS62350 EVM board Software Texas Instruments provides software to assist in evaluating this EVM. The software can be installed from the supplied CD or downloaded from the Texas Instruments Web site at www.ti.com. Setup This section describes the jumpers and connectors on the EVM as well as how to properly connect, set up, and use the TPS62350EVM-201. - Page 3 C master has its own pullup or operates from a voltage that is different than the input voltage of the TPS62350. The Texas Instruments USB interface adapter provides an active pullup; therefore, do not install a jumper when using the adapter supplied with the EVM.

Figure 11 show the board layout for the TPS62350EVM-201 PCB. The nodes with high-switching frequencies and currents are kept as short as possible to minimize trace inductance. Careful attention has been given to the routing of high-frequency current loops and a single-point grounding scheme is used. See the data sheet for specific layout guidelines. -
