The IR3508 Phase IC combined with any IR XPhase3
Control IC provides a full featured and flexible way to
phase of a multiphase converter. The XPhase3
architecture results in a power supply that is smaller, less

XPHASE3 TM PHASE IC
DESCRIPTION
TM
implement a power solution for the latest high performance CPUs and ASICs. The “Control” IC provides
overall system control and interfaces with any number of “Phase” ICs which each drive and monitor a single
TM
expensive, and easier to design while providing higher efficiency than conventional approaches.
The IR3508 disables its current sense amplifiers when entering power savings mode. The recommended use
for these Phase ICs is for applications without adaptive voltage positioning where two or more power stages
will be operating in power savings mode.
