Three-Phase  Buck Controller with Integrated Gate Drivers and Power Good

   The CS5301 is a three–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 V2 control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use.
