PD94718 XPHASE DESCRIPTION TM VR 10/11 CONTROL IC The IR3084 Control IC combined with an IR XPhaseTM Phase IC provides a full featured and flexible way to implement a complete VR10 or VR11 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.
FEATURES • • • • • • • • • • • • • • • • • 1 to X phase operation with matching Phase IC Supports both VR11 8-bit VID code and extended VR10 7-bit VID code 0.
5% Overall System Setpoint Accuracy VID Select pin sets the DAC to either VR10 or VR11 VID Select pin selects either VR11 or legacy VR10 type startups Programmable VID offset and Load Line output impedance Programmable VID offset function at the Error Amp’s non-inverting input allowing zero offset Programmable Dynamic VID Slew Rate ±300mV Differential Remote Sense Programmable 150kHz to 1MHz oscillator Enable Input with 0.
