GENERAL DESCRIPTION  
12  
DELAY  
The ADP31901 is a highly efficient, multiphase, synchronous  
buck switching regulator controller optimized for converting a  
5 V (ADP3190A) or 12 V (ADP3190) main supply into the core  
supply voltage required by high performance Intel processors.  
The part uses an internal 6-bit DAC to read a voltage identifica-  
tion (VID) code directly from the processor, which is used to  
set the output voltage between 0.8375 V and 1.6 V. The devices  
use 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 relationship 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 ADP3190 is a replacement for the ADP3188. A built-in  
shunt regulator allows the part to be connected to the 12 V  
system supply through a series resistor.  
The ADP3190 includes programmable, no-load offset and slope  
functions to adjust the output voltage as a function of the load  
current, so it is always optimally positioned for a system  
transient. The ADP3190 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.  
The device is specified over the commercial temperature  
range of 0°C to 85°C and is available in a 28-lead TSSOP and  
a 28-lead QSOP.
