General Description
   The NCP5380 is a highly efficient, single−phase, synchronous buck switching regulator controller. With its integrated drivers, the NCP5380 is optimized for converting the silver box 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 chipset.
