way to implement multiphase power solutions. The Control IC provides overall system control and interfaces
with any number of IR3527 Phase ICs which each drive and monitor 2 phases of a Synchronous Buck
converter.
The IR3527 implement an independent power savings function for each power stage and sequential phase
timing for use in single output multiphase converters. When power saving mode is enabled, the power stage
will disable its output thus eliminating its switching loss while proper converter operation is maintained by the
single power stage or in conjunction with other converter power stages. The IR3527 current sense amplifiers
remain active when in power savings to support adaptive voltage positioning.
