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.

QFN32

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

ADP3211 also provides accurate and reliable current overload

protection and a delayed power−good output. The IC supports

On−The−Fly (OTF) output voltage changes requested by the chip−set.

The ADP3211 has a boot voltage of 1.1 V for IMVP−6.5

applications in CPU mode. The ADP3211A has a boot voltage of

1.2 V in CPU mode.
