Notes 1: The total peak output current is the peak value of the peak currents flowing through all the applicable ports.
2: The total average output current is the average value measured over 100 ms flowing through all the applicable ports.
3: The peak output current is the peak current flowing in each port.
4: The average output current is an average value measured over 100 ms.
