It’s V2™ control 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 price/performance solutions for their end products. 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 protects the processor dur- ing potentially catastrophic events like overvoltage (OVP) and short circuit. The OVP feature is part of the V2™ architec- 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 MOSFETs do not overheat or self destruct. 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.
