Product Summary

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.
