The ZY8160 is an intelligent, fully programmable multiphase step-down point-of-load DCDC module integrating digital power conversion and intelligent power management. When used with ZM7300 Series Digital Power Managers, the ZY8160 completely eliminates the need for external components for sequencing, tracking, protection, monitoring, and reporting. All parameters of the ZY8160 are programmable via 2 the industry-standard I C communication bus and can be changed by a user at any time during product development and service.

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. 1.5, 5-May-2011 www.power-one.com Page 3 of 29 ZY8160 60A DC-DC Intelligent POL 8V to 14V Input * 0.5V to 2.75V Output Data Sheet Vo [V] 3.0 2.75 2.5 2.1 2.0 1.5 1.0 0.5 8.0 9.0 10.5 9.6 10.0 11.0 12.0 13.0 14.0 Vi [V] Figure 1.
