The CS51312 is a synchronous dual NFET Buck Regulator Controller. It is designed to power the core logic of the latest high performance CPUs and ASICs from a single 12V input. It uses the V2 TM control method to achieve the fastest possible transient response and best overall regulation. It incor- porates many additional features required to ensure the proper opera- tion and protection of the CPU and Power system. The CS51312 provides the industry’s most highly integrated solution, minimizing external compo- nent count, total solution size, and cost. The CS51312 is specifically designed to power Intel’s Pentium® II processor and includes the following features: 5-bit DAC with 1.2% tolerance, Power-Good output, overcurrent hic- cup mode protection, overvoltage protection, VCC monitor, Soft Start, adaptive voltage positioning, adap- tive FET non-overlap time, and remote sense. The CS51312 will oper- ate over a 9V to 20V (VCC2) range using either single or dual input volt- age and is available in 16 lead narrow body surface mount package.
