General Description
http://onsemi.com
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 .
The NCP5380/A uses a multimode architecture. It provides
programmable switching frequency that can be optimized for

efficiency depending on the output current requirement. In addition,
the NCP5380/A includes a programmable load line slope function to
adjust the output voltage as a function of the load current so that the
core voltage is always optimally positioned for a load transient. The
NCP5380/A also provides accurate and reliable current overload
protection and a delayed power ? good output. The IC supports
On ? The ? Fly (OTF) output voltage changes requested by the chipset.
The NCP5380 is specified over the temperature range of 0 ° C to
85 ° C, while the NCP5380A extends the temperature range to ? 40 ° C to
100 ° C. The NCP5380/A is available in a 32 ? lead QFN.
