ADP3206 - 2-/3-/4-Phase Synchronous Buck Controller

General Description

The ADP3206 is a highly efficient multiphase synchronous buck-switching regulator controller optimized for converting the notebook main supply into the core supply voltage required by IMVP-5 Intel processors.

Key Features

  • Selectable 2-, 3-, or 4-phase operation at up to 1 MHz per phase 6-bit digitally programmable 0.8375 V to 1.6 V output ±10 mV DAC accuracy over temperature Logic-level PWM outputs for interface to external high power drivers Active current/thermal balancing between phases Built-in power good/crowbar blanking supports on-the-fly VID code changes Programmable deep sleep offset and deeper sleep reference voltage Programmable soft transient control to minimize inrush currents during output voltage c.
