The CS51311 is a synchronous dual NFET Buck Regulator Controller. It is designed to power the core logic of the latest high performance CPUs. It uses the V2™control method to achieve the fastest possible transient response and best overall regulation. It incorporates many additional features required to ensure the proper operation and protection of the CPU and Power system. The CS51311 provides the industry's most highly integrated solution, minimizing external component count, total solution size, and cost.The CS51311 is specifically designed to power Intel's PentiumâCC monitor, soft start, adaptive voltage position- ing, adaptive FET non-overlap time, and remote sense. The CS51311 will operate over an 8.4V to 14V range and is available in 14 lead narrow body surface mount package.
