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 TM multiphase converter. The XPhase3 architecture implements a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches. TM FEATURES • • • • • • • • • • • • • • • • • 1 to X phase operation with matching Phase IC VID Select pin configures AMD 5 or 6 bit PVID, Intel VR11 with/out startup to 1.1V Boot voltage 0.
