Description
Power-One‟s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZY7010L is an intelligent, fully programmable 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 ZY7010L completely eliminates the need for external components for sequencing, tracking,
protection, monitoring, and reporting. All parameters of the ZY7010L 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.

The solder exemption
refers to all the restricted materials except lead in solder. These materials are Cadmium (Cd), Hexavalent chromium
(Cr6+), Mercury (Hg), Polybrominated biphenyls (PBB), Polybrominated diphenylethers (PBDE), and Lead (Pb) used anywhere except in
solder.

The evaluation board is available in only one configuration: ZM7300-KIT-HKS.
Example:
ZY7010LG-T2:
A 100-piece reel of RoHS compliant POL converters with the output voltage setpoint of
1.0% or 20mV, whichever is greater. Each POL converter is labeled ZY7010LG.

ZY7010L is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.
At the negative output current (bus terminator mode) efficiency of the ZY7010L 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.
