100ns Controller Transient

architecture delivers the fastest transient  
response (100ns), and best overall voltage  
regulation in the industry today. It’s fea-  
ture rich design gives end users the maxi-  
mum flexibility to implement the best  
ture and does not require any additional  
components. During short circuit, the  
controller pulses the MOSFETs in a “hic-  
cup” mode (3% duty cycle) until the fault  
is removed. With this method, the

destruct.  
The CS5165H 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 on board oscillator can be pro-  
grammed up to 1MHz to give the design-  
er maximum flexibility in choosing exter-  
nal components and setting systems  
costs.  
The CS5165H is designed for use in both  
single processor desktop and multipro-  
cessor workstation and server applica-  
tions. The IC can be powered from either  
single or dual 5V, 12V power supplies.  
The CS5165H’s current sharing capability  
allows the designer to build multiple par-  
allel and redundant power solutions for  
multiprocessor systems.  
The CS5165H 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.
