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.
