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   Benefits
     
  • Single-chip solution. Fully compatible with the Intel® IMVP-6.5 CPU and GMCH chipset voltage regulator specifications integrated MOSFET drivers.
 
  • Improved efficiency.
  • Input voltage range of 3.3V to 22V.
 
  • Improved efficiency.
  • ±7mV worst-case differentially sensed core voltage error overtemperature.
 
  • Improved efficiency.
  • Automatic power-saving modes maximizes efficiency during light load operation.
 
  • Improved efficiency.
  • Soft transient control reduces inrush current and audio noise.
 
  • Current and audio reduction.
  • Independent current limit and load line setting inputs for additional design flexibility.
 
  • Improved design flexibility.
  • Built-in power-good masking supports voltage identification (VID) OTF transients.
 
  • Improved efficiency.
  • 7-bit, digitally programmable DAC with 0V to 1.5V output.
 
  • Improved efficiency.
  • Short-circuit protection.
 
  • Improved protection.
  • Current monitor output signal.
 
  • Improved efficiency.
  • This is a Pb-free device. Fully RoHS compliant and 32-lead QFN.
 
  • Added benefits.
Applications
