GENERAL DESCRIPTION
The ADP3182 is a highly efficient multiphase, synchronous, buck-switching regulator controller optimized for converting a 12 V main supply into a high current, low voltage supply for use in point-of-load (POL) applications. It 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 1-, 2-, or 3-phase operation, allowing for the construction of up to three complementary buckswitching stages. The ADP3182 also provides accurate and reliable short-circuit protection and adjustable current limiting.

FEATURES
   Selectable 1-, 2-, or 3-phase operation at up to 1 MHz per
      phase
   ±2% worst-case differential sensing error over temperature
   Externally adjustable 0.8 V to >5 V output from a 12 V supply
   Logic-level PWM outputs for interface to external high
      power drivers
   Active current balancing between all output phases
   Built-in power good/crowbar functions
   Programmable short-circuit protection with programmable
      latch-off delay

APPLICATIONS
   Auxiliary supplies
   DDR memory supplies
   Point-of-load modules
