Specifications apply at the input voltage from 8V to 14V, output load from 0 to 5A, ambient temperature from 0°C
to 70°C, output capacitance consisting of 2x22µF low ESR ceramic, and default performance parameters settings
unless otherwise noted.

Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves
shown in paragraph 5.5.

ZY8105 is a step-down converter, thus the output voltage is always lower than the input voltage.
At the negative output current (bus terminator mode) efficiency of the ZY8105 degrades resulting in increased internal power dissipation.
