NCP5422ADR2G 直流-直流转换控制器

安森美半导体为直流－直流转换应用提供创新优化的解决方案,如主板VRM应用、48 V电信设备板载功率传输和新兴42V汽车系统中的多相控制器。

The NCP5422ADR2G is a dual N-channel synchronous buck regulator controller. It contains all the circuitry required for two independent buck regulators and utilizes the V2 control method to achieve the fastest possible transient response and best overall regulation, while using the least number of external components. The NCP5422ADR2G features out-of-phase synchronization between the channels, reducing the input filter requirement. The NCP5422ADR2G also provides undervoltage lockout, Soft Start, built in adaptive non-overlap time and hiccup mode overcurrent protection.
