NCP5422A

Dual Out−of−Phase

Synchronous

Buck Controller

with Current Limit

The NCP5422A is a dual N−channel synchronous buck regulator

controller. It contains all the circuitry required for two independent

buck regulators and utilizes the V

control method to achieve the

fastest possible transient response and best overall regulation, while

using the least number of external components. The NCP5422A

features out−of−phase synchronization between the channels,

reducing the input filter requirement. The NCP5422A also provides

undervoltage lockout, Soft Start, built in adaptive non−overlap time

and hiccup mode overcurrent protection.
