ADP3168 - 4-Phase Synchronous Buck Controller

The ADP3168 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.

• Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase ±10 mV worst-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 0.8375 V to 1.6 V output Programmable short-circuit protection with programmable latch-off delay.
