Description
Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate
Bus Architecture (IBA). 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. Performance parameters of
the ZY2140 are 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.
