Use the following instructions to perform the
overvoltage test:
- Set the input supply voltage VIN to 48 V and current limit of 10 A.
- Enable the power supply.
- Now, gradually increase the VIN voltage to observe the overvoltage cutoff
response of TPS48110-Q1 using an oscilloscope.
Figure 5-8 shows
overvoltage cutoff response of TPS48110-Q1 on TPS48110Q1EVM Evaluation Board.
