Use the following instructions to perform the overcurrent test on the TPS48110Q1EVM:
- Enable the control input INP (TP6) of the main MOSFETS.
- By default, the EVM is configured for 5-A overcurrent protection.
- Now, load the output with rheostat or electronic load and gradually increase the load current to observe the overload behavior of TPS48110-Q1.
- Place jumper J3 at other settings to test at various overcurrent limits.
Figure 5-6 and Figure 5-7 show test waveforms for an overcurrent fault.
