NCP433数据手册集成电路（IC）的DC-DC开关控制器规格书PDF

描述 Description

The NCP432 and 433 are low Ron MOSFET controlled by an external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, thanks to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC's on the battery when not used.

特性 Features

• 1.0 V3.6 V Operating Range
• 37 m P MOSFET at 3.3 V
• DC Current up to 1.5 A
• Active High EN Pin
• Output Auto-Discharge for the NCP433

应用 Application

• Load Management
• Smartphones, Tablets, Digital cameras

简介

NCP433属于集成电路（IC）的DC-DC开关控制器。由制造生产的NCP433DC-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。
