Product Description

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.
Features
•Single−Chip Solution
♦Fully Compatible with the Intel® IMVP−6.5™ CPU and GMCH Chipset Voltage Regulator Specifications Integrated MOSFET Drivers
•Input Voltage Range of 3.3 V to 22 V
•±7 mV Worst−Case Differentially Sensed Core Voltage Error Overtemperature
•Automatic Power−Saving Modes Maximize Efficiency During Light Load Operation
•Soft Transient Control Reduces Inrush Current and Audio Noise
•Independent Current Limit and Load Line Setting Inputs for Additional Design Flexibility
•Built−in Power−Good Masking Supports Voltage Identification (VID) OTF Transients
•7−Bit, Digitally Programmable DAC with 0 V to 1.5 V Output
•Short−Circuit Protection
•Current Monitor Output Signal
•This is a Pb−Free Device
•Fully RoHS Compliant
•32−Lead QFN
Applications
•Notebook Power Supplies for Next Generation Intel Chipsets
•Intel Netbook Atom Processors
