Description
The ZY7120 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
ZY7120 completely eliminates the need for external components for sequencing, tracking, protection, monitoring,
and reporting. All parameters of the ZY7120 are programmable via the industry-standard I2C communication bus
and can be changed by a user at any time during product development and service.
