Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZY8160 is an intelligent, fully programmable multiphase step-down point-of-load DC-
DC 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.

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.
