EVM Connectors

3 EVM Connectors
This section describes the connectors, jumpers, and test points on the EVM as well as how to connect, set up,
and properly use the EVM.

3.1 EVM Test Points

Table 3-1 lists the test points and functional descriptions. All TPS3899 pins have a corresponding test point on
the EVM. These test points are located close to the pins for more accurate measurements.
