描述 Description

The ZY7007 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 ZY7007 completely eliminates the need for external components for sequencing, tracking, protection, monitoring, and reporting. All parameters of the ZY7007 are programmable via the industry-standard I2C communication bus and can be changed by a user at any time during product development and service.
