architecture delivers the fastest transient  
response (100ns), and best overall voltage  
regulation in the industry today. It’s fea-

price/performance solutions for their end

architecture and  
feature is part of the V  
does not require any additional compo-  
nents. During short circuit, the controller  
pulses the MOSFETs in a “hiccup” mode  
(3% duty cycle) until the fault is removed.  
With this method, the MOSFETs do not  
overheat or self destruct.

Excess of 1Mhz Operation  
5 Bit DAC with 1% Tolerance  
Power Good Output With  
Internal Delay  
The CS5165 has been carefully crafted to  
maximize performance and protect the  
processor during operation. It has a 5-bit  
DAC on board that holds a ±1% tolerance  
over temperature. Its on board pro-  
grammable soft start insures a control  
start up, and the FET nonoverlap circuit-  
ry ensures that both FETs do not conduct  
simultaneously.  
The CS5165 is designed for use in both  
single processor desktop and multipro-  
cessor workstation and server applica-  
tions. The CS5165’s current sharing capa-  
bility allows the designer to build multi-  
ple parallel and redundant power solu-  
tions for multiprocessor systems.  
The CS5165 contains other control and  
protection features such as Power Good,  
ENABLE, and adaptive voltage position-  
ing. It is available in a 16 lead SOIC wide  
body package.
