Description
The ZY7015 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
ZY7015 completely eliminates the need for external components for sequencing, tracking, protection, monitoring,
and reporting. All parameters of the ZY7015 are programmable via the industry-standard I2C communication bus
and can be changed by a user at any time during product development and service.

1 ZY7015 is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.
2 At the negative output current (bus terminator mode) efficiency of the ZY7015 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 5.5.
