NCP1581数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

The NCP1581 Synchronous Buck Controller IC is designed to provide a simple synchronous buck regulator for on-board DC-DC applications in a 14-pin SOIC. The NCP1581 is designed specifically for tracking applications by providing the track input.The NCP1581 operates at a fixed internal 400 kHz switching frequency allowing the use of small external components. The device features a programmable soft start set by an external capacitor, under-voltage lockout and output under-voltage detection that latches off the device when an output short is detected.

简介

NCP1581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NCP1581DC-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。
