GENERAL DESCRIPTION  
PRECISION  
REFERENCE  
OD  
The ADP3207A1 is a high efficiency, multiphase, synchronous,  
buck-switching regulator controller optimized for converting  
notebook battery voltage into the core supply voltage required  
by high performance Intel processors. The part uses an internal  
7-bit digital-to-analog converter (DAC) to read voltage  
identification (VID) code directly from the processor that sets  
the output voltage. The phase relationship of the output signals  
can be programmed to provide 1-, 2-, or 3-phase operation,  
allowing for the construction of up to three interleaved buck-  
switching stages.

Figure 1.  
The chip 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 ADP3207A is specified over the extended commercial  
temperature range of 0°C to 100°C and is available in a  
40-lead LFCSP.  
The ADP3207A uses a multimode architecture to drive the  
logic-level PWM outputs at a programmable switching  
frequency that can be optimized depending on the output  
current requirement. The part switches between multiphase and  
single-phase operation to maximize its effectiveness under all load  
conditions. In addition, the ADP3207A includes a programmable  
slope function to adjust the output voltage as a function of the  
load current. As a result, it is always best positioned for a system  
transient.
