It is designed to power 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 regulation. It incorporates many additional features required to ensure the proper operation and protec- tion of the CPU and Power system. The CS51313 provides the industry’s most highly integrated solution, minimizing external component count, total solution size, and cost. The CS51313 is specifically designed to power Intel’s Pentium® II processor and includes the following features: 5-bit DAC with 1.2% tolerance, Power-Good output, overcurrent hiccup mode protec- tion, over voltage protection, VCC moni- tor, Soft Start, adaptive voltage position- ing and adaptive FET non-overlap time. A precision reference trimmed to 1% is also externally available for use by other regulators. The CS51313 will operate over an 8.4V to 14V range and is avail- able in 16 lead narrow body surface mount package.
