The ADP3193A1 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  
performance 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.  
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- or  
3-phase operation, allowing for the construction of up to three  
complementary buck switching stages.  
The ADP3193A has a built-in shunt regulator that allows the  
part to be connected to the 12 V system supply through a series  
resistor.  
The ADP3193A is specified over the extended commercial  
temperature range of 0°C to 85°C and is available in a  
32-lead LFCSP.  
The ADP3193A 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  
ADP3193A also provides accurate and reliable short-circuit  
protection, adjustable current limiting, and delayed power-good  
output that accommodates on-the-fly output voltage changes  
requested by the CPU.
