Description
The ADP3191/ADP3191A1 are highly efficient, multiphase, synchronous buck switching regulator controllers optimized for converting a 5 V or 12 V 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 ±14.5 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 on-the-fly VID code changes 6-bit digitally programmable 0.8375 V to 1.6 V output Programmable short circuit protection with programmab.
