CS5165A
5−Bit Synchronous CPU Buck Controller
The CS5165A synchronous 5−bit NFET buck controller is optimized to manage the power of the next generation Pentium II processors. It’s V2t 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 CS5165A 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 startup, and the FET nonoverlap circuitry ensures that both FETs do not conduct simultaneously.
