NCP3030中文资料NCP3030: Synchronous PWM Controller数据手册ONSEMI规格书

描述 Description

The NCP3030 is a PWM device designed to operate from a wide input range and is capable of producing an output voltage as low as 0.6 V. The NCP3030 provides integrated gate drivers and an internally set 1.2 MHz (NCP3030A) or 2.4 MHz (NCP3030B) oscillator. The NCP3030 also has an externally compensated transconductance error amplifier with an internally fixed soft-start. Protection features include lossless current limit and short circuit protection, output overvoltage protection, output undervoltage protection, and input undervoltage lockout. The NCP3030 is currently available in a SOIC-8 package.

简介

NCP3030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NCP3030DC-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。
