The CS51313 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.
required to ensure the proper operation and protection 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 protection, over voltage protection, VCC monitor, Soft Start, adaptive voltage positioning and adaptive FET non-overlap time. A precision reference trimmed to 1% is also externally available f.
