Two−Phase PWM Controller  
with Integrated Gate  
Drivers for VRM 8.5  
The CS5308 is a secondgeneration, twophase step down  
controller that incorporates all control functions required to power  
next generation processors. Proprietary multiphase architecture  
guarantees balanced load current distribution and reduces overall

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

These enhancements provide greater design flexibility, facilitate use  
and reduce output voltage jitter.

The multiphase 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.
