ZY8160 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 ZY8160 degrades resulting in increased internal power dissipation.
Therefore maximum allowable negative current is limited to 40A.
