3.1.2 Power Up Into Short

Follow the instructions to perform the power-up into short test:

  1. Set the input supply voltage VIN to 54V and current limit to 5A. Keep the power supply OFF.
  2. Connect the supply between VIN2 (connector J13) and PGND (connector J11).
  3. Short the output of the EVM to ground. For example, short VOU2 (connector J14) to PGND (connector J12) through a cable.
  4. Turn ON the power supply.
