2.3.4 Wakeup into Short Test

Use the following instructions to perform wakeup into short test.

  1. Set the input supply voltage VIN to 12 V and current limit of 10 A. Turn OFF the power supply.
  2. Short the output of the device for example, VOUT to GND with a shorter cable.
  3. Turn ON the power supply.
