Product Description

The ADP3211 is a highly efficient, single−phase, synchronous buck switching regulator controller. With its integrated driver, theADP3211 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. TheADP3211 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−6.5applications in CPU mode. The ADP3211A has a boot voltage of1.2 V in CPU mode. The ADP3211 is specified over the extended commercial temperature range of −10°C to 100°C and is available in a 32−lead QFN.
