GENERAL DESCRIPTION
The ADP3192A1 is a highly efficient, multiphase, synchronous buck-switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 8-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.5 V and 1.6 V.

FEATURES
    Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase
    ±7.7 mV worst-case differential sensing error over temperature
    Logic-level PWM outputs for interface to external high power drivers
    Fast enhanced PWM (FEPWM) flex mode for excellent load transient performance
    Active current balancing between all output phases
    Built-in power-good/crowbar blanking supports on-the-fly VID code changes
    Digitally programmable 0.5 V to 1.6 V output supports both VR10.x and VR11 specifications
    Programmable short-circuit protection with programmable latch-off delay
   
APPLICATIONS
    Desktop PC power supplies for next generation Intel® processors VRM modules
