Buck Controller for
12 V Only Applications
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 12 V input. It uses the2 ™ 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 CS51312 provides the industry’s most highly
integrated solution, minimizing external component count, total
solution size, and cost.
The CS51312 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,
overvoltage protection, VCC monitor, Soft Start, adaptive voltage
positioning, adaptive FET non−overlap time, and remote sense. The
CS51312 will operate over a 9.0 V to 20 V (VCC2) range using either
single or dual input voltage and is available in 16 lead narrow body
surface mount package.
