Page 1
... The ZY8105 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 ZM7000 Series Digital Power Managers, the ZY8105 completely eliminates the need for external components for sequencing, tracking, protection, monitoring, and reporting. All parameters of the ZY8105 are programmable via the industry-standard communication bus and can be changed by a user at any time during product development and service ...

... ZY8105 is a step-down converter, thus the output voltage is always lower than the input voltage the negative output current (bus terminator mode) efficiency of the ZY8105 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 ...
