NCP1573中文资料Buck Controller数据手册ONSEMI规格书

描述 Description

The NCP1573 is a low voltage buck controller. It provides the control for a DC-DC power solution producing an output voltage as low as 0.980 V over a wide current range. The NCP1573-based solution is powered from 12 V with the output derived from a 2-7 V supply. It contains all required circuitry for a synchronous NFET buck regulator using the V2™ control method to achieve the fastest possible transient response and best overall regulation. NCP1573 operates at a fixed internal 200 kHz frequency and is packaged in an SO-8.This device provides Power Good with delay and built-in adaptive non-overlap.

简介

NCP1573属于集成电路（IC）的PMIC-稳压器-DCDC开关式控制器。由制造生产的NCP1573DC-DC 开关控制器PMIC（电源管理集成电路）DC 到 DC 开关式控制器是用于高效率电路的稳压 IC，其配置为生成高于（突升或步升）或低于（突降或步降）输入电源的输出电源电压。其他拓扑结构可能包括：降压-升压、反激、正激、Cuk、SEPIC、全桥、半桥和推挽式。这些器件不同于需要最小电压并“烧尽”多余电压的线性稳压器。
