3 TPS65313-EVM Jumper Settings
The TPS65313-EVM has many jumpers to make the EVM more flexible. Setting these jumpers correctly
for the correct function of the EVM is important.
Table 2 lists the jumpers and their functionality. The EVM
is preconfigured with default jumper settings and users can power up the regulators without any jumper
modifications. To understand more about the jumper functionality, see the schematic diagrams in
Section 8 .
