CS5422
Dual OutofPhase
Synchronous
Buck Controller
with Current Limit
The CS5422 is a dual N
channel synchronous buck regulator
controller. It contains all the circuitry required for two independent
buck regulators and utilizes the V
2
control method to achieve the
fastest possible transient response and best overall regulation, while
using the least number of external components. The CS5422 features
out
of
phase synchronization between the channels, reducing the
input filter requirement. The CS5422 also provides undervoltage
lockout, Soft Start, built in adaptive FET non
overlap and hiccup
mode overcurrent protection. The part is available in a 16 Lead SO
Narrow or 24 Lead Fused SO Wide package allowing the designer to
minimize solution size.
