Product details

Description

The ADP3189 1 is a highly efficient multi-phase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors.

Features

Selectable 2-, 3-, 4-, or 5-phase operation at up to 1 MHz per phase ±7.7 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 Digitally programmable 0.5 V to 1.6 V output.
supports both VR10.x and VR11 specifications Programmable short-circuit protection with programmable latch-off delay Th.
