XPHASE3TM VR11.0 & AMD PVID CONTROL IC
DESCRIPTION
The IR3500 Control IC combined with an XPHASE3TM 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 XPhaseBTM architecture implements a power supply that is smaller, less
expensive, and easier to design while providing higher efficiency than conventional approaches.
FEATURES
q 1 to X phase operation with matching Phase IC
q 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
q 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
q Simplified VR Ready output provides indication of proper operation and avoids false triggering
. Small thermally enhanced 32L 5mm x 5mm MLPQ package
