The block diagram of a typical application of ZY7120 point-of-load converters (POL) is shown in Figure 25. The
system includes multiple POLs and a ZM7000 series Digital Power Manager (DPM). All POLs are connected to
the DPM and to each other via a single-wire SD (sync/data) line. The line provides synchronization of all POLs to
the master clock generated by the DPM and simultaneously performs bidirectional data transfer between POLs
and the DPM. Each POL has a unique 5-bit address programmed by grounding respective address pins. To
enable the current share, CS pins of POLs connected in parallel are linked together.
There are three groups of POLs in the application, groups A, B, and group C. A group is defined as a number of
POLs interconnected via OK pins. Grouping of POLs enables users to program, control, and monitor multiple
POLs simultaneously and execute advanced fault management schemes.
The complete schematic of the application is shown in Figure 26.
