ZY8140 is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.
At the negative output current (bus terminator mode) efficiency of the ZY8140 degrades resulting in increased internal power dissipation.
Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves
shown in paragraph 5.5.
