NCP5380A Description
The NCP5380/A is a highly efficient, single−phase, synchronous buck switching regulator controller. With its integrated drivers, the NCP5380/A 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.
