5.2 Configuring the Output Current
The TPS92010EVM-631 can be configured for different output current levels. Soldering of 0402 parts is
required to do this. Table 2 below shows the resistor values necessary for various current levels. Figure 3
shows the location of these resistors on the top side of the PSU board.
