NCP5331FTR2G [Onsemi]

The NCP5331 is a second-generation, two-phase, buck controller that incorporates advanced control functions to power 64-bit AMD Athlon processors and low voltage, high current power supplies. Proprietary multiphase architecture guarantees balanced load-current sharing, reduces output voltage and input current ripple, decreases filter requirements and inductor values, and increases output current slew rate. Traditional enhanced V2 has been combined with an internal PWM ramp and voltage feedback directily from Vcore to the internal PWM comparator. These features and enhancements deliver the fastest transient response, reduce output voltage jitter, provide greater design flexibility and porability, and minimize overall solution cost.
