UL 60950-1/CSA 22.2 No. 60950-1-07 Second
Edition, IEC 60950-1: 2005, and EN 60950-1:2006
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZY2140 is an intelligent, fully programmable step-down point-of-load DC-DC module
integrating digital power conversion and power management. The ZY2140 completely eliminates the need for
external components for sequencing, tracking, protection, monitoring, and reporting. Performance parameters of
the ZY2140 are programmable by pin strapping and an external resistor and can be changed by the user at any
time during product development and service without a need for a communication bus.

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.
Example:
ZY2140G-R3:
A 30-piece tray of RoHS compliant POL converters. Each POL converter is labeled
ZY2140G.
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 POL converter.

At the negative output current (bus terminator mode) efficiency of the ZY2140 degrades resulting in increased internal power dissipation.
Maximum allowable negative current is limited to 40A.
2
ZY2140 is a step-down converter, thus the output voltage is always lower than the input voltage as show in
Error! Reference source not
found..
3
Digital PWM has an inherent quantization uncertainty of ±6.25mV that is not included in the specified static regulation parameters.
