IR3502A
DATA SHEET
XPHASE3
TM
CONTROL IC
DESCRIPTION
The IR3502A control IC combined with an
XPHASE3
TM
Phase IC provides a full featured and flexible way
to implement a complete VR11.0 and VR11.1 power solution. The IR3502A provides overall system control
and interfaces with any number of Phase ICs, each driving and monitoring a single phase. The XPhase3
TM
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
Small thermally enhanced 32L 5mm x 5mm MLPQ package
RoHS Compliant
