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.
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.

... 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. ...
