NCP5332A Two-Phase Buck Controller with Integrated Gate Drivers and 5-Bit DAC
The NCP5332A is a second-generation, two-phase step down controller which incorporates all control functions required to power high performance processors and high current power supplies. Proprietary multi-phase architecture guarantees balanced load current distribution and reduces overall solution cost in high current applications. Enhanced V2TM control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use. The NCP5332A is a second-generation PWM controller because it optimizes transient response by combining traditional Enhanced V 2 with an internal PWM ramp and fast-feedback directly from VCORE to the internal PWM comparator. These enhancements provide greater design flexibility, facilitate use and reduce output voltage jitter. The NCP5332A multi-phase architecture reduces output voltage and input current ripple, allowing for a significant reduction in filter size and inductor values with a corresponding increase in inductor current slew rate. This approach allows a considerable reduction in input and output capacitor requirements, as well as reducing overall solution size and cost.
