Figure 3. Typical Application Schematic of Multiple Output System with Digital Power Manager and I²C Interface

The schematic of a typical application of a ZM7300 digital power manager (DPM) is shown in Figure 3.

The system includes four groups of Z-One Point Of Load converters (POLs). A group is defined as one

or more POL converters interconnected via OK pins. Grouping of the POLs enables users to program

advanced fault management schemes and define margining functions, monitoring, startup behavior, and

reporting conventions.

All Z-One POL converters are connected to the DPM and to each other via a single-wire

synchronization/data (SD) line. The line provides synchronization of all POL converters to the master

clock generated by the DPM and simultaneously carries bidirectional data transfer between POL

converters and the DPM. The DPM communicates via the I²C bus with the host system and/or the

Graphical User Interface.

In this application, besides Z-One POL converters, the DPM also controls and monitors two auxiliary

devices – a Voltage Regulation Module (VRM) and a Low Dropout Regulator (LDO). While these

devices are not Z-One compliant and may not even be manufactured by Power-One, they are integrated

into the system by communicating with the DPM via their Enable pins connected to ENX outputs of the

DPM. In addition, the DPM monitors status of the auxiliary devices via its PGX inputs connected to

Power Good and Error Flag outputs of the auxiliary devices. The DPM can control and monitor four or

more independent auxiliary devices.
