The ADP3212/NCP3218 is a highly efficient, multiphase, synchronous buck switching regulator controller. With its integrated drivers, the ADP3212/NCP3218 is optimized for converting the notebook battery voltage into the core supply voltage required by high performance Intel processors. An internal 7-bit DAC is used to read a VID code directly from the processor and to set the CPU core voltage to a value within the range of 0.3 V to 1.5 V. The ADP3212/NCP3218 is programmable for 1-, 2-, or 3-phase operation. The output signals ensure interleaved 2- or 3-phase operation.
