It is designed to pow- er the core logic of the latest high performance CPUs. It uses the V2 TM control method to achieve the fastest possible transient response and best overall regula- tion. It incorporates many addi- tional features required to ensure the proper operation and protec- tion of the CPU and power sys- tem. The CS5166 provides the industry’s most highly integrat- ed 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 pro- tection, VCC monitor, Soft Start, adaptive voltage positioning, over-voltage protection, remote sense and current sharing capa- bility. The CS5166 will operate over a 4.15 to 14V range and is available in a 16 lead wide body surface mount package.
