3.4.5 Start-Up With Short-Circuit On Output

Use the following instructions to perform startup into short test.

  1. Set the current limit to 4.5 A by installing the J4/J11 jumper in position 1-2.
  2. Set the input power supply voltage to 58 V and current limit of 9 A. Turn OFF the power supply.
  3. Short the output of the device (for example, VOUT to GND with a shorter cable).
  4. Turn ON the power supply.
  5. Verify the device behavior for startup into short as shown in Figure 3-4.
