www.DataSheet4U.com CS5421 Dual Out−of−Phase Synchronous Buck Controller with Remote Sense The CS5421 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 CS5421 features out−of−phase synchronization between the channels, reducing the input filter requirement. The CS5421 also provides undervoltage lockout, Soft Start, built in adaptive FET non−overlap and remote sense capability. The part is available in a 16 Lead SO Narrow package allowing the designer to minimize solution size.
