CS5332
TwoPhase Buck Controller
with Integrated Gate
Drivers for VRM 9.0
The CS5332 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 V2
control architecture provides the fastest possible transient response,
excellent overall regulation, and ease of use.
The CS5332 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.
