Description
Power-One’s point-of-load converters are recommended for use with regulate d 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
the industry-standard I2C communication bus and can be changed by a user at any time during product
development and service.
