Controllers | CS5166H

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 V^2™ 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.

The CS5166H is specifically designed to power Intel's Pentium ^â II processor and includes the following features: 5-bit DAC with 1% tolerance, Power-Good output, adjustable hiccup mode over-current protection, V_CC monitor, Soft Start, adaptive voltage positioning, over-voltage protection, remote sense and current sharing capability.

The CS5166H will operate over a 4.15 to 20V range using either single or dual input voltage and is available in a 16 lead wide body surface mount package.
