ADP3211, ADP3211A
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.
The ADP3211 uses a multi ? mode architecture. It provides
programmable switching frequency that can be optimized for
efficiency depending on the output current requirement. In addition,

the ADP3211 includes a programmable load line slope function to
adjust the output voltage as a function of the load current so that the
core voltage is always optimally positioned for a load transient. The
