Product Description
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.
