NCP5332A Two-Phase Buck Controller with Integrated Gate Drivers and 5-Bit DACThe NCP5332A is a second−generaTIon, two−phase step downcontroller which incorporates all control funcTIons required to powerhigh performance processors and high current power supplies.Proprietary mulTI−phase architecture guarantees balanced load currentdistribuTIon and reduces overall solution cost in high currentapplications. Enhanced V2] control architecture provides the fastestpossible transient response, excellent overall regulation, and ease ofuse. The NCP5332A is a second−generation PWM controller becauseit optimizes transient response by combining traditional Enhanced V2with an internal PWM ramp and fast−feedback directly from VCORE tothe internal PWM comparator. These enhancements provide greaterdesign flexibility, facilitate use and reduce output voltage jitter.The NCP5332A multi−phase architecture reduces output voltageand input current ripple, allowing for a significant reduction in filtersize and inductor values with a corresponding increase in inductorcurrent slew rate. This approach allows a considerable reduction ininput and output capacitor requirements, as well as reducing overallsolution size and cost.
