TPS2306 Dual Sequencing Hot Swap Power Manager
The board has been designed with two thru-hole patterns and two jumpers on each of the two supply outputs.
These can be used for the installation of large-value electrolytic capacitors to simulate the load capacitance of
the target application. The TPS2306 EVM ships from the factory with 220-
μ
F caps (C15 and C17) and 330-
μ
F
caps (C16 and C18) installed for functional demonstration. In addition, banana jacks J1 through J3 are available
for easy hook-up of the user
s resistive or electronic loads for simulation of the application
s load current levels,
if desired.
Test points are provided throughout the EVM circuit for waveform monitoring. The test point connections are
listed in Table 1.

Switch S1 is used for easy selection from among the preset fault timer values available in the default
configuration. The timing capacitors installed correlate to different combinations of the load capacitors, as
detailed in Table 7. In addition, a fourth timing capacitor slot is open at C14 for installation of a user-selected
timing cap for even larger loads.
