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 ZY1115 is an intelligent, fully programmable step-down point-of-load DC-DC module
integrating digital power conversion and intelligent power management. The ZY1115 completely eliminates the
need for external components for sequencing, tracking, protection, monitoring, and reporting. Performance
parameters of the ZY1115 are programmable by pin strapping and external resistor and capacitor and can be
changed by a user at any time during product development and service without a need for a communication bus.

At the negative output current (bus terminator mode) efficiency of the ZY1115 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.

ZY1115 is a step-down converter, thus the output voltage is always lower than the input voltage as show in Figure 1.

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