1 _{ZY7007 is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.}
2 _{At the negative output current (bus terminator mode) efficiency of the ZY7007 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.
