CS51311

Synchronous CPU

Buck Controller for 12 V

and 5.0 V Applications

The CS51311 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 V2™ 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 CS51311

provides the industry’s most highly integrated solution, minimizing

external component count, total solution size, and cost.

The CS51311 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,

VCC monitor, soft start, adaptive voltage positioning, adaptive FET

non−overlap time, and remote sense. The CS51311 will operate over

an 8.4 V to 14 V range and is available in 14 lead narrow body surface

mount package.
