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. 2 ZD-01674 Rev. 1.2, 02-Jul-10 www.power-one.com Page 3 of 30 ZY8160 60A DC-DC Intelligent POL 8V to 14V Input  0.5V to 2.75V Output Data Sheet Figure 1.
