CS5166

www.DataSheet4U.com CS5166 5−Bit Synchronous CPU Controller with Power Good and Current Limit The CS5166 is a synchronous dual NFET buck controller. It is designed to power the core logic of the latest high performance CPUs. It uses 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 CS5166 provides the industry’s most highly integrated solution, minimizing external component count, total solution size, and cost. The CS5166 is specifically designed to power Intel’s Pentium®II processor and includes the following features: 5−bit DAC with 1.0% tolerance, Power Good output, adjustable hiccup mode overcurrent protection, VCC monitor, Soft Start, adaptive voltage positioning, overvoltage protection, remote sense and current sharing capability. The CS5166 will operate over a 4.15 to 14 V range using either single or dual input voltage and is available in a 16 lead wide body surface mount package.
