DATA SHEET
XPHASE3TM CONTROL IC
DESCRIPTION
The IR3502 control IC combined with an XPHASE3TM Phase IC provides a full featured and flexible way to
implement a complete VR11.0 and VR11.1 power solution. The IR3502 provides overall system control
and interfaces with any number of Phase ICs, each driving and monitoring a single phase. The XPhase3TM
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
• 0.5% overall system set point accuracy
• Daisy-chain digital phase timing provides accurate phase interleaving without external components
• Programmable 250kHz to 9MHz clock oscillator frequency provides per phase switching frequency of
250kHz to 1.5MHz
• 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 10V/us
• Programmable constant converter output current limit during soft start
• Hiccup over current protection with delay during normal operation
• Central over voltage detection and latch with programmable threshold and communication to phase ICs
• Over voltage signal output to system with overvoltage detection during powerup and normal operation
• Load current reporting
• Single NTC thermistor compensation for correct current reporting, OC Threshold, and Droop
• Detection and protection of open remote sense line
• Open control loop protection
• IC bias linear regulator controller
• Programmable VRHOT function monitors temperature of power stage through a NTC thermistor
• Remote sense amplifier with true converter voltage sensing
• Simplified VR Ready (VRRDY) output provides indication of proper operation
• Small thermally enhanced 32L 5mm x 5mm MLPQ package
• RoHS compliant
