DATA SHEET
XPHASE3 TM PHASE IC
DESCRIPTION
The IR3505 Phase IC combined with an IR XPhase3
TM
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
implement power solutions 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.
