5.5 Test Methods
Procedure
Connect the power supplies and load to the TPS2410 test card as shown in Table 2 . Loading less than 30
A is safe for IRl3713S. The load can be a test load or the actual system load.

The EVM has a few operating modes to view the system response. The user can make modifications to
the EVM to test in other ways.
