ISL6729
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.
