DATA SHEET
XPHASE3
TM
VR11.0 & AMD PVID CONTROL IC
DESCRIPTION
The IR3500 Control IC combined with an
xPHASE3
TM
Phase IC provides a full featured and flexible way to
implement a complete VR11.0 or AMD PVID 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 X
Phase3
architecture implements 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
VID Select pin configures AMD 5 or 6 bit PVID, Intel VR11 with/out startup to 1.1V Boot voltage
0.5% overall system set point accuracy
Programmable 250kHz to 9MHz Daisy-chain digital phase timing clock oscillator frequency provides a
per phase switching frequency of 250kHz to 1.5MHz without external components
Programmable Dynamic VID Slew Rate
Programmable VID Offset or No Offset
Programmable Load Line Output Impedance
High speed error amplifier with wide bandwidth of 30MHz and fast slew rate of 12V/us
Programmable converter current limit during soft start, hiccup with delay during normal operation
Central over voltage detection with programmable threshold and communication to phase ICs
Over voltage signal output to system with overvoltage detection during powerup and normal operation
Detection and protection of open remote sense line and open control loop
IC bias linear regulator control with programmable output voltage and UVLO
Programmable VRHOT function monitors temperature of power stage through a NTC thermistor
Remote sense amplifier with true converter voltage sensing and less than 50uA bias current
Simplified VR Ready output provides indication of proper operation and avoids false triggering
Small thermally enhanced 32L 5mm x 5mm MLPQ package
