ADP3194 Product details

GENERAL DESCRIPTION
The ADP31941 is a highly efficient, multiphase, synchronous buck switching regulator controller optimized for converting a 5 V or 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 6-bit DAC to read a voltage identification (VID) code directly from the processor that is used to set the output voltage between 0.8375 V and 1.6 V. The device uses a multimode PWM architecture to drive the logic-level outputs at a programmable switching frequency that can be optimized for VR size and efficiency. The phase relationship of the output signals can be programmed to provide 2-, 3-, or 4-phase operation, allowing for the construction of up to four complementary buck switching stages.

FEATURES
   Selectable 2-, 3-, or 4-phase operation
   Up to 1 MHz per phase
   ±9.5 mV worst-case differential sensing error
      over temperature
   Logic-level PWM outputs for interface to external
      high power drivers
   PWM Flex-ModeTM architecture for excellent load
      transient performance
   Active current balancing between all output phases
   Built-in power good/crowbar blanking supports OTF VID
      code changes
   6-bit digitally programmable 0.8375 V to 1.6 V output
   Programmable short circuit protection with programmable
      latch-off delay

APPLICATIONS
   Desktop PC power supplies for
      Next-generation Intel® processors
      VRM modules
   Games consoles
