CS5422

Dual Out−of−Phase

Synchronous

Buck Controller

with Current Limit

http://onsemi.com

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 ™ control method to achieve the

SO−16

D SUFFIX

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.
