CS5303

Three-Phase Buck

Controller with Integrated

Gate Drivers

The CS5303 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 V

control architecture provides the fastest possible transient response,

excellent overall regulation, and ease of use.

CASE 751F

The CS5303 multi–phase architecture reduces output voltage and

input current ripple, allowing for a significant reduction in inductor

values and a corresponding increase in inductor current slew rate. This

approach allows a considerable reduction in input and output capacitor

requirements, as well as reducing overall solution size and cost.
