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.

• 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 3.3V to 22V.
• ±7mV worst-case differentially sensed core voltage error overtemperature.
• Automatic power-saving modes maximizes 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 0V to 1.5V output.
• Short-circuit protection.
• Current monitor output signal.
• This is a Pb-free device.Fully RoHS compliant and 32-lead QFN.
