DATA SHEET
CONTROL IC
The IR3082A Control IC combined with an IR XPhase
Phase IC provides a full featured and flexible way
general purpose multiphase applications. The XPhase
architecture results in a power supply that is

to implement a power solution. The “Control” IC provides overall system control and interfaces with any
number of “Phase ICs” which each drive and monitor a single phase of a multiphase converter. With
simple 5 bit voltage programming and a few external components, the IR3082A is also well suited for

smaller, less expensive, and easier to design while providing higher efficiency than conventional
approaches.
