Overview

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 V2t control method to achieve the fastest possible transient response and best overall regulation, while using the least number of external components.

Key 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. Features.
ăV2 Control Topology.
ăHiccup Mode Overcurrent Protection.
ă150 ns Transient Response.
ăProgrammable Soft-Start.
ă100% Duty Cycle for Enhanced Transient Response.
ă150 kHz to 600 kHz Programmable Frequency Operation.
