Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZY7115 is an intelligent, fully programmable 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 ZY7115 completely eliminates the need for external components for sequencing, tracking,
protection, monitoring, and reporting. All parameters of the ZY7115 are programmable via the industry-standard
I 2 C communication bus and can be changed by a user at any time during product development and service.
