CS5302 General Description


The CS5302 is a twophase step down controller which incorporates all control functions required to power high performance processors and high current power supplies. Proprietary multiphase architecture guarantees balanced load current distribution and reduces overall solution cost in high current applications. Enhanced V2TM control architecture provides the fastest possible transient response,excellent overall regulation, and ease of use.

The CS5302 multiphase 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.
