CS5323

www.DataSheet4U.com 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 V2™ 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.
