3.1.4 Overvoltage Protection Test

Use the following instructions to perform the overvoltage test:

  1. Set the input supply voltage VIN to 48 V and current limit of 10 A
  2. Enable the power supply.
  3. Now, gradually increase the VIN voltage to observe the overvoltage cutoff response of TPS48000-Q1 using an oscilloscope.
