CS5323
Three-Phase Buck
Controller with 5-Bit DAC
The CS5323 is a three–phase step down controller that incorporates
all control functions required to power next generation processors.
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 multi–phase architecture reduces input and output filter ripple,
allowing for a reduction in filter size and inductor values with a
corresponding increase in the output inductor current slew rate.
