CS5166

CS5166 CS5166 5-Bit Synchronous CPU Controller with Power-Good and Current Limit Description The CS5166 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 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% tolerance, Power-Good output, adjustable hiccup mode over-current protection, VCC monitor, Soft Start, adaptive voltage positioning, over-voltage protection, remote sense and current sharing capability. The CS5166 will operate over a 4.15 to 14V range and is available in a 16 lead wide body surface mount package.
