Product Summary

The NCP5422AG is a dual channel synchronous buck regulator controller. It contains all the circuitry required for two independent buck regulators and utilizes the V2 control method to achieve the fastest possible transient response and best overall regulation, while using the least number of external components. The NCP5422AG features out of phase synchronization between the channels, reducing the input filter requirement. The NCP5422AG also provides undervoltage lockout, Soft Start, built in adaptive overlap time and hiccup mode overcurrent protection.
