CS5308
TwoPhase PWM Controller
with Integrated Gate
Drivers for VRM 8.5
The CS5308 is a second
generation, two
phase step down
controller that incorporates all control functions required to power
next generation processors. 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 CS5308 is a second generation
PWM controller because it optimizes transient response by combining
traditional Enhanced V
2
with an internal PWM ramp and
fast
feedback directly from V
CORE
to the internal PWM comparator.
These enhancements provide greater design flexibility, facilitate use
and reduce output voltage jitter.
The multi
phase 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.
The CS5308 includes VTT monitoring and timing, VTT Power
Good (VTT
PGD
), Power Good (PWRGD), and internal MOSFET gate
drivers to provide a “fully integrated solution” to simplify design,
minimize circuit board area, and reduce overall system cost.
