... Reduces board space, system cost and complexity, and time to market Description 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. ...

... 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 Figure 1. 3 Digital PWM has an inherent quantization uncertainty of ±6.25mV that is not included in the specified static regulation parameters. ...
