EVM Setup www.ti.com EVM Setup This section describes how to properly connect and setup the TPS7A26EVM-021, including the jumpers and connectors on the EVM board. Input/Output Connectors and Jumper Descriptions 2.1.1 J1 – IN Input power supply voltage connector. Twist together the positive input lead and ground return lead from the input power supply, and keep them as short as possible to minimize input inductance. -
