Description
The NCP5422A dual N-channelsynchronous buck rcgulatorcontroller Dual Out-of-PhaseSynchronousBuck Controllerwith Current Limit
The NCP5422A/3 is a dual N-channelsynchronous buck rcgulatorcontroller. It contains all the circuitry required for two independentbuck regulators and utilizes the V 2 control method to achieve thefastest possible transient response and best overall regulation, wbileusing the least number of external components.The NCP5422A/3featurcs out-of-phasc synchronization betwcen the channels,reducing the input filter requirement.The NCP5422A/3 also providesundervoltage lockout, Soft-Start, built in adaptive non-overlap timeand biccup mode overcurrent protection.
