CS5422
Dual Out−of−Phase
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.
