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 V2™ 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.
