2.3.5 Overvoltage Cut-off Test

Use the following instructions to perform overvoltage protection test.

  1. Remove input TVS diodes.
  2. Set the input supply voltage VIN to 12 V and current limit of 5 A. Apply the supply between input connectors J1 and J3 and enable the power supply.
  3. Set the load resistance to 24 Ω and connect between VOUT and GND.
  4. Increase the input supply VIN from 12 V to 18 V and observe the waveforms using an oscilloscope.
