ADI ADP3193JCPZ-RL

控制器，Intel VR10，VR1112V0.5V ~ 1.6V

Overview

The ADP31931 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. It uses an internal 8-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.5 V and 1.6 V.

Selectable 2- or 3-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 Enhanced PWM flex mode 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 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
