3.1 EVM Test Points

Table 3-1 lists the EVM test points as well as their functional descriptions. All TPS3704x-Q1 pins have a corresponding test point on the EVM. These test points are located close to the pins for more accurate measurements. In addition to the test points listed below, the EVM also has four additional GND test points.
