3.4.4 Output Short-Circuit Protection Test

Follow the instructions to verify the output short-circuit protection feature of the device:

  1. Set the current limit to 1 A by installing the J4/J11 jumper in position 7-8.
  2. Set the input power supply voltage to 50 V and current limit to 6 A. Turn ON the power supply.
  3. Short the output of the device (for example, VOUT to GND with a shorter cable).
  4. Verify the output short-circuit response waveform as shown in Figure 3-3.
