GENERAL DESCRIPTION

The ADP3168 is a highlyefficient, multiphase, synchronous buck switching  regulator controller optimized for converting a 12V main supply into the core supply voltage required by high

performance Intel processors.

FEATURES

Selectable 2-,3-, or 4-phase operation at up to 1 MHz per phase

±10 mVworst-case differential sensing error over temperature

Logic-level PWM outputs for interface to external high power drivers

Active current balancing between all output phases

Built-in Power Good/crowbar blanking supports

On-the-fly VID code changes

6-bit digitally programmable 0.8375V to 1.6 V output

Programmable short-circuit protection with programmablelatch-off delay

APPLICATIONS

Desktop PC power supplies for:

   Next generationIntel® processors

   VRM modules
