with Current Limit
The NCP5422A/3 is a dual Nchannel synchronous buck regulator
controller. It contains all the circuitry required for two independent
buck regulators and utilizes the V

fastest possible transient response and best overall regulation, while
using the least number of external components. The NCP5422A/3
features outofphase synchronization between the channels,
reducing the input filter requirement. The NCP5422A/3 also provides
undervoltage lockout, SoftStart, built in adaptive nonoverlap time
and hiccup mode overcurrent protection.
