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 V 2 ? 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 V CORE 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.
