3.2 Modified Configuration Results

The following test was performed with an EVM board that was modified by removing the output capacitors, and is meant to demonstrate the fast-trip overcurrent protection of the TPS7H2140-SEP. For the purposes of demonstrating the fast-trip feature, the output of the device was short-circuited to collect Figure 3-9. Purposefully short-circuiting any output of the EVM is not recommended and rapidly causes the device to overheat.
