The CS51312 is a synchronous dual NFET Buck Regulator Controller. It is designed to power the core logic of the latest high performance CPUs and ASICs from a single 12V input. It uses the V2TM control method to achieve the fastest possible transient response and best overall regulation. It incorporates a 5-bit DAC with 1.2% tolerance for 200ns transient loop response. It also includes a fast shutdown feature that can turn off the switches in a short time to provide protection against overcurrent conditions.
