ADP3209JCPZ

Product Summary

The ADP3209JCPZ is a highly efficient, single-phase, synchronous buck switching regulator controller. With its integrated drivers, the ADP3209JCPZ is optimized for converting the notebook battery voltage to render the supply voltage required by high performance Intel chipsets. An internal 5-bit DAC is used to read a VID code directly from the chipset and to set the GMCH core voltage to a value within the range of 0.4 V to 1.25 V. The applications of the ADP3209JCPZ inlcude Notebook power supplies for next-generation Intel chipsets.
