2.1.1 EVM Connections

Referencing the EVM connections described in Table 3-1, the recommended test setup to evaluate the TPS51375 is shown in Figure 3-1. Working at an ESD-protected workstation, make sure that any wrist straps, boot straps, or mats are connected and referencing the user to earth ground before handling the EVM.
