... 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: ZY1120-K1. Example: ZY1120G-T3: A 50-pieces reel of RoHS compliant POL converters. Each POL converter is labeled ZY1120G. 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 ...

... Therefore maximum allowable negative current under specific conditions is 20% lower than the current determined from the derating curves shown in paragraph 5.5. 2 ZY1120 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. ...
