Description

The CS5166H 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 V2TM 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 CS5166H provides the industry’s most highly integrated solution, minimizing external component count, total solution size, and cost.
