MARKING  
General 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.  
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.
