Description
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 ZM7000 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 I2C communication bus
and can be changed by a user at any time during product development and service.

1 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.
2 Packaging option is used only for ordering and not included in the part number printed on the POL converter label.
3 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.
2. Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long-
term reliability, and cause permanent damage to the converter.

1 ZY7010L 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 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.
