ADP3211:IMVP6.5, 7-Bit, Programmable, Single-Phase, Synchronous Buck Controller
The ADP3211 is a highly efficient, single-phase synchronous buck switching regulator controller. With its integrated driver, the ADP3211 is optimized for converting the notebook battery voltage to the supply voltage required by high performance Intel chipsets. An internal 7-bit DAC is used to read a VID code directly from the chip-set or the CPU and to set the GMCH render voltage or the CPU core voltage to a value within the range of 0 V to 1.5 V.
