Controllers | CS5308

The CS5308 is a second–generation, two–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 CS5308 is a second generation PWM controller because it optimizes transient response by combining traditional Enhanced V²™ with an internal PWM ramp and fast–feedback directly from VCORE to the internal PWM comparator. These enhancements provide greater design flexibility, facilitate use and reduce output voltage jitter.

The multi–phase architecture reduces input and output filter ripple, allowing for a significant reduction in filter size and inductor values with a corresponding increase in the output 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.

The CS5308 includes VTT monitoring and timing, VTT Power Good (VTT_PGD), Power Good (PWRGD), and internal MOSFET gatedrivers to provide a 'fully integrated solution' to simplify design, minimize circuit board area, and reduce overall system cost.
