CS5165H  
5-Bit Synchronous CPU  
Buck Controller  
The CS5156H synchronous 5–bit NFET buck controller is optimized  
to manage the power of the next generation Pentium II processors. It’s

and best overall voltage regulation in the industry today. It’s feature rich  
design gives end users the maximum flexibility to implement the best  
price/performance solutions for their end products.  
DIAGRAM  
The CS5156H has been carefully crafted to maximize performance  
and protect the processor during operation. It has a 5–bit DAC on  
board that holds a ±1.0% tolerance over temperature. Its on board  
programmable Soft Start insures a control start up, and the FET  
nonoverlap circuitry ensures that both FETs do not conduct simultaneously.  
The on board oscillator can be programmed up to 1.0 MHz to give  
the designer maximum flexibility in choosing external components  
and setting systems costs.

The CS5156H protects the processor during potentially catastrophic  
events like overvoltage (OVP) and short circuit. The OVP feature is  
part of the V architecture and does not require any additional

components. During short circuit, the controller pulses the MOSFETs  
in a “hiccup” mode (3.0% duty cycle) until the fault is removed. With  
this method, the MOSFETs do not overheat or self destruct.  
The CS5156H is designed for use in both single processor desktop  
and multiprocessor workstation and server applications. The IC can be  
powered from either single or dual 5.0 V, 12 V power supplies. The  
CS5156H’s current sharing capability allows the designer to build multiple  
parallel and redundant power solutions for multiprocessor systems.  
The CS5156H contains other control and protection features such as  
Power Good, ENABLE, and adaptive voltage positioning. It is  
available in a 16 lead SOIC wide body package.
