The Typical Application block diagram illustrates how the

ISL6729 may be used for an interleaved power converter. In

this example, three clock signals of equal duty cycle, but

phased 120º apart, are applied to separate power stages.

Each phase shares a common voltage feedback signal, but

uses separate current feed back signals from each power

stage for regulation. Excellent current sharing behavior is

assured since each phase must produce the same peak

current. Accuracy is determined by the variation of the

output inductor value and the feedback components.

Multiple output power supplies can be created in a similar

fashion. Only one clock signal is required if in-phase

operation is desired. Each stage may be independently

controlled using separate voltage and current feedback

loops.
