CS5302
TwoPhase Buck Controller
with Integrated Gate
Drivers and 4Bit DAC
The CS5302 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
2
control architecture provides the fastest possible transient response,
excellent overall regulation, and ease of use.
The CS5302 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.
