The ADP31981 is a highly efficient, multiphase, synchronous buck  
switching regulator controller optimized for converting a 12 V  
main supply into the core supply voltage required by high per-  
formance Intel processors. It uses an internal 8-bit DAC to read  
a voltage identification (VID) code directly from the processor,  
which is used to set the output voltage between 0.5 V and 1.6 V.

Figure 1.  
The ADP3198 has a built-in shunt regulator that allows the part  
to be connected to the 12 V system supply through a series resistor.  
This device uses a multimode PWM architecture to drive the  
logic-level outputs at a programmable switching frequency that  
can be optimized for VR size and efficiency. The phase relation-  
ship of the output signals can be programmed to provide 2-, 3-,  
or 4-phase operation, allowing for the construction of up to  
four complementary buck switching stages.  
The ADP3198 is specified over the extended commercial  
temperature range of 0°C to 85°C and is available in a  
40-lead LFCSP.  
The ADP3198 also includes programmable no load offset and  
slope functions to adjust the output voltage as a function of the  
load current, optimally positioning it for a system transient. The  
ADP3198 also provides accurate and reliable short-circuit  
protection, adjustable current limiting, and a delayed power-  
good output that accommodates on-the-fly output voltage  
changes requested by the CPU.
