Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). The ZY1120 is an intelligent, fully programmable step-down point-of-load DC-DC module
integrating digital power conversion and intelligent power management. The ZY1120 completely eliminates the
need for external components for sequencing, tracking, protection, monitoring, and reporting. Performance
parameters of the ZY1120 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.
