CS5332  
Two-Phase Buck Controller  
with Integrated Gate  
Drivers for VRM 9.0  
The CS5332 is a two–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.  
The CS5332 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.
