CS5165

5−Bit Synchronous CPU

Buck Controller

The CS5165 synchronous 5−bit NFET buck controller is optimized to

manage the power of the next generation Pentium II processors. It’s

V2™ control architecture delivers the fastest transient response (100 ns),

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.

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 ±1.0% 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 CS5165 protects the processor during potentially catastrophic

events like overvoltage (OVP) and short circuit. The OVP feature is

part of the V2 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 CS5165 is designed for use in both single processor desktop and

multiprocessor workstation and server applications. The CS5165’s

current sharing capability allows the designer to build multiple

parallel and redundant power solutions for multiprocessor systems.

The CS5165 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.
