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 V2TM 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.
