CS5323
Three−Phase Buck
Controller with 5−Bit DAC
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
possible transient response, excellent overall regulation, and ease of
use.
allowing for a reduction in filter size and inductor values with a
corresponding increase in the output inductor current slew rate.
