GENERAL DESCRIPTION  
The ADP3156 is a highly efficient synchronous buck switching  
regulator controller optimized for converting the 3.3 V or 5 V  
main supply into lower supply voltages required on the mother-  
boards of Pentium® III and other high performance processor  
systems. The ADP3156 uses a current mode, constant off-time  
architecture to drive two external N-channel MOSFETs at a  
programmable switching frequency that can be optimized for  
size and efficiency. It also uses a unique supplemental regulation  
technique called active voltage positioning to enhance load  
transient performance. Active voltage positioning results in a  
DC/DC converter that provides the best possible transient re-  
sponse using the minimum number of output capacitors and  
smallest footprint. Unlike voltage-mode and standard current-  
mode architectures, active voltage positioning adjusts the output  
voltage as a function of the load current so that it is always  
optimally positioned for a system transient.  
CMP  
The ADP3156 contains a linear regulator controller that is  
designed to drive an external N-channel MOSFET. This linear  
regulator is used to generate the auxiliary voltages (AGP, GTL,  
etc.) required in most motherboard designs, and has been de-  
signed to provide a high bandwidth load-transient response. A  
pair of external feedback resistors sets the linear regulator out-  
put voltage.

The ADP3156 provides accurate and reliable short circuit  
protection and adjustable current limiting. It also includes an  
integrated overvoltage crowbar function to protect the micro-  
processor from destruction in case the core supply exceeds the  
nominal programmed voltage by more than 15%.
