Data Sheet No. PD94705 IR3080 XPHASETM VRD10 CONTROL IC WITH VCCVID & OVERTEMP DETECT DESCRIPTION The IR3080 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VRD 10 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. The XPhaseTM architecture results in a power supply that is smaller, less expensive, and easier to design while providing higher efficiency than conventional approaches. The IR3080 is intended for desktop applications and includes the VCCVID and VRHOT functions required for proper system operation. FEATURES • 6 bit VR10 compatible VID with 0.
