Overview

ADP3209D 5-Bit, Programmable, Single-Phase, Synchronous Buck Controller The ADP3209D is a highly efficient, single−phase, synchronous buck switching regulator controller.

With its integrated drivers, the ADP3209D is optimized for converting the notebook battery voltage to render the supply voltage required by high performance Intel chipsets.

An internal 5−bit DAC is used to read a VID code directly from the chipset and to set the GMCH core voltage to a value within the range of 0.4 V to 1.25 V.

Key Features

  • Single.
  • Chip Solution.
  • Fully Compatible with the Intel® GMCH Chipset Voltage Regulator Specifications.
