Dual Out-of-Phase Synchronous Buck Controller

The NCP5422A is a dual N-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 NCP5422A features out-of-phase synchronization between the channels, reducing the input filter requirement. The NCP5422A also provides undervoltage lockout, Soft Start, built in adaptive non-overlap time and hiccup mode overcurrent protection.
