Using the EVM Kit to Evaluate the TPS2306 HSPM
Procedures similar to the steps of Section 3.2.2 (Functional Test) for functional test of the EVM board can be
used to continue evaluation of the TPS2306 device. Alternatively, to have the TPS2306 turn on the outputs
automatically after insertion, see Section 4.7, Automatic Power-Up, for setup instructions. Also, input supply and
output load characteristics can be modified to better approximate the user
s system parameters. See Section 4
for details on modifying the EVM configuration.

Reconfiguring the EVM
4.1
Pre-Configured Fault Timer Settings
The TPS2306 EVM is easily modified to simulate different load characteristics. Onboard capacitors C15
C18
are available for easy hookup to their respective EVM outputs. Switch S1 selects the appropriate timeout period
for the supplied load caps. Table 7 summarizes some of the preset timer settings that should be used for different
load combinations.
